What inferences can you make about the melting points of the different substances and the motion of their particles, based on the data?
The wax has the greatest melting point than butter and cheese after the wax the cheese has the greater melting point than butter.
Melting point is the state at which the solid is converted into liquid on application of heat. Wax has greatest force of attraction among the wax particles which increases the melting point of the wax, that means higher temperature is required to break the bonds between the wax atoms. Butter has the lowest melting point, there is weak force of attraction between butter atoms the bonds between them break because of application of very little amount of heat. On application of heat on the cheese initially the cheese cube does not change in shape but become flattened due to application of heat. Hence, the wax has the greatest melting point than butter and cheese after the wax the cheese has the greater melting point than butter.Learn more about melting point:

Answer:dew is formed on grass
Explanation:Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.

Pls mark as Brainliest
Explanation:
Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops
As fall begins, we have lots of mornings with dew on the grass. To explain this, we start with the fact that air contains water in the gas phase, called water vapor. Dew is made of liquid water that has condensed from that water vapor.
Dew occurs when objects cool, such as when drops of liquid form on the outside of an ice-cold drink glass. Dew forms when the object, such as the glass, cools down to the dew point temperature.
Water molecules in the air continually bombard surfaces, like blades of grass. Some of the molecules stick, forming a very thin film of water. This film may not last long, as the water is also evaporating. The evaporation rate depends on the water temperature, which equals the temperature on the grass.
So condensation depends on the state of the atmosphere (primarily temperature and moisture), while evaporation depends on the temperature of the object. If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops.
Each night the weather report includes the temperature and the dew point temperature. If the two temperatures are close, dew is likely during the night. Because wind and cloudy skies keep the ground from cooling, dew also tends to form on calm nights with clear skies.

This is a schematic for a clothes dryer appliance. This appliance dries clothes primarily by converting--
A) Thermal energy into electrical energy
B) Electrical energy into thermal energy and mechanical energy
C) Kinetic energy into thermal energy
D) Electrical energy into mechanical energy
The cloth dryer appliance works on the energy transformation from electrical energy into mechanical energy and thermal energy. Hence, option B is correct.
What is energy transformation?According to energy conservation law, energy can neither be created nor be destroyed but it can be transformed from one form to the other. Thus, energy lost by one form can be gained in other form.
In electrical devices, electrical energy is converting to various other forms. For instance, in lamps, electrical energy is converted to the light energy. Similarly in fan electrical energy is converted to the mechanical energy.
In a cloth dryer the electrical energy is converted to the mechanical energy to make it operate and this further produces the thermal energy sufficient to dry the clothes.

Answer:
Solids keep their shape and cannot be compressed. Let us see if the particle model can help us understand why solids behave in this way.
In a solid, the particles are packed close to each other in fixed positions. They are locked into place, and this explains why solids have a fixed shape. Look at the following images of sodium chloride (table salt). Do you remember the formula for sodium chloride?
Macroscopic view of sodium chloride
Submicroscopic view of sodium chloride
Table salt crystals are hard and have a fixed shape.
Can you see how the chloride atoms (purple) alternate with the sodium atoms (yellow) in a fixed arrangement?
Take a good look at the picture of the particles in a solid (table salt) above. You will see that they are packed in a regular arrangement. There are very small spaces between the particles in a solid.
Particles are held together by forces of attraction. In solids, these forces are strong enough to hold the particles firmly in position.
Does that mean the particles in a solid do not move at all? No. The particles in a solid move a little bit. They vibrate in their fixed positions. The more energy the particles have, the faster and more strongly they vibrate.
Do you see how we have used the particle model of matter to explain the properties of solids that we can observe? For example, the particles in solids are closely packed and have strong forces between them explains why solids have a fixed shape and you cannot compress them.
The liquid state
An important characteristic of liquids is that they flow. They fill containers they are poured into. Liquids are also not very compressible. How can these properties be explained?
Orange juice is a liquid, which can be poured.
In the liquid state, particles do not have fixed positions. They move about freely, but they stay close together because the forces of attraction between them are quite strong, but not as strong as in solids.
Have you noticed how a liquid always takes the shape of the container it is in? Within the liquid, the particles slip and slide past each other. This is why liquid flows. Their particles are free to move around, filling the spaces left by other particles. Look at the image of the juice being poured. Let's zoom in and have a look at what the particles are doing as the juice is poured.
The particles in a liquid have small spaces between them, but not as small as in solids. The particles in a liquid are loosely arranged which means they do not have a fixed shape like solids, but they rather take the shape of the container they are in.
The speed at which the particles move around inside the liquid depends on the energy of the particles. When we heat a liquid, we are giving the particles more energy and speeding them up.
In gases, the particles move at even greater speeds.
The gaseous state
Gases spread out quickly to fill all the space available to them. Think of when you blow up a balloon. The air that you blow into the balloon fills up the whole balloon. A gas will fill the entire space that is available to it. This is because the particles in a gas have no particular arrangement.
Gases do not have a fixed shape. Think about the balloon again: the gas fills the entire space inside the balloon. You can squeeze the balloon, changing the shape.
Gases fill the space available to them.
Gases do not have a fixed shape.
Gas particles move very fast, much faster than in solids and liquids. The particles in a gas possess a lot of energy.
Have you ever tried to compress the gas in a syringe or in a bicycle pump? Why do you think you can compress the gas?
In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.

what is the relationship between the evolution of marsupials and the movement of earths tectonic plate? 8th Grade No links or files Please
The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.
What is meant by evolution ?Evolution is defined as the gradual and cumulative processes by which the traits of biological population and the diversities changed over time.
Here,
The movement of tectonic plates of earth resulted in the continents to break apart into various isolated parts. During this movement of the tectonic plates, the group of organisms that were living at some continents got split from the actual habitats and were driven to different isolated community of organisms.
As a result, the marsupials who were inbreeding within their habitats were reproductively isolated to different parts of the earth. Thus they got adapted to the new areas and resulted in the creation of new species which is called the evolution of marsupials.
Hence,
The relationship between the evolution of marsupials and the movement of earths tectonic plate is that the marsupials migrated to different continents during the drift.
