1. Solid Definition: firm and stable in shape; not liquid or fluid.
Example: A hard kitchen countertop.
2. Crystalline Solid Definition: Crystalline solids consist of atoms, ions and molecules arranged in definite and repeating three-dimensional patterns in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Example: Salt, diamonds
3. Amorphous Solid Definition: an amorphous or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal.
Example: rubber, plastic, and gels
4. Liquid Definition: A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a constant volume independent of pressure. As such, it is one of the four fundamental states of matter, and is the only state with a definite volume but no fixed shape.
Example: Water, juice, rain
5. Surface Tension Definition: the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
Example: Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface.

How much energy is required to melt a 500. gram block of iron? The heat of vaporization is 6090 J/g and the heat of fusion is 247 J/g.
3.05x10 6 J
2.47x10 2 J
1.23x10 5 J
6.09x10 3 J
Answers
Answer:
Heat required = 1.23×10⁵J
Explanation:
Given:
Mass (m) = 500 gram
Specific heat = 6,090 J/g
heat of fusion = 247 J/g.
Find:
Heat required
Computation:
Heat required = 247 J/g× 500 g
Heat required = 1.23×10⁵J

Answers
Answer:
At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.
Explanation:
During meiosis, a diploid cell (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).
These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

What suprising result is explained using this model
Answers
Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.

If carbon monoxide (CO) leaked into your home, would you predict that if would float to the
top of the room or stay near the floor? Answer the same question for carbon dioxide (CO2),
would it float or sink?
Answers
Answer: It will sink
Explanation:
To solve this we must be knowing each and every concept related to carbon monoxide. Therefore, carbon monoxide float to the top of the room.
What is carbon monoxide?When the carbon in fuels burns inefficiently, a toxic gas known as carbon monoxide is created. It is emitted both naturally—from forest fires or volcanic eruptions, for example—and artificially—through procedures. It is lighter than the air.
By attaching to and removing oxygen from myoglobin, carbon monoxide reduces the oxygen storage capacity in muscle cells, which is another way it upsets the body's processes. If carbon monoxide (CO) leaked into your home, carbon monoxide float to the top of the room. Numerous manufacturing and medicinal items employ carbon monoxide.
Therefore, carbon monoxide float to the top of the room.

Ali rolled a ball down a hill. This graph shows the kinetic and potential energy of the moving ball.
A line graph The graph is titled Mechanical Energy and shows an inverse relationship between Potential energy and Kinetic Energy. The Y axis is Potential energy (J). The X axis is Kinetic energy (J). The point of the graph are as such: (0, 5); (1, 4); (2, 3); (3, 2); (4, 1); (5, 0)
According to the graph, what is the mechanical energy of the ball?
A. 0 J
B. 5 J
C. 20 J to 25 J
D. 0 J to 4 J
Answers
Answer:D
Explanation:
Hope I helped
When we plot the relation between kinetic energy and potential energy, we get an inverse line. The mechanical energy of an object is the sum of kinetic energy and potential energy. . The mechanical energy here is 5 J.
What is mechanical energy?Mechanical energy of an objects is the sum of it energy of motion and the stored energy of position, that is the sum of kinetic energy and potential energy.
Kinetic energy of an object result from its motion whereas potential energy results from the position of the object. Both kind of energy depends on the mass of the object.
Kinetic energy also depends on the velocity of the object and potential energy depends on the height and gravity experienced by it. Both are thus directly proportional to the mass of the object.
Here, all the points in the graph have a total energy of 5 J . for example for the first point the sum is 0 +5= 5J. Similarly, all the points have a total of 5 J.
Therefore, the mechanical energy of the system is 5J and the option B is correct.

Answer:
C. Pesticides protect our crops, but some European countries have
linked them to thyroid disorders.
Explanation:
Researches involving human or sometimes animals are subject to critical decision making.
They can easily trespass on the fundamental rights of people and some other issues.
The use of pesticides on a crop which can lead to thyroid disorder is an ethical dilemma. In this case, the pesticide helps to prevent crop loss due to the invasion of pests. This will boost food production and ensure food is availableLikewise, the application of the pesticide causes thyroid issues.

Answers
Answer:
The answer is 2.0 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 4 g
volume = 2 cm³
We have
[tex]density = \frac{4}{2} \\ [/tex]
We have the final answer as
2.0 g/cm³Hope this helps you
Answer:
D = 2 g/cm³
Explanation:
Density = mass over volume
D= m/v
Step 1: Define
m= 4 grams
v= 2 cm³
Step 2: Substitute and Evaluate
D= 4 g/2 cm³
D= 2 g/cm³
