Due to property of conduction, conductor allows electrons and electric current to move easily,insulators prevent electric current from moving, electric current is the flow of an electrical charge in a circuit and electric circuit provides a path for electrons to flow.
What is conduction?Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

73 gram of HCl was filluted by adding 144gram of water.how many gram atom of hydrogen are present in the dilute acid?
Answers
Mass of Hydrogen atoms : 18 g
Further explanationGiven
73 gram of HCl
144gram of H₂O
Required
Mass (gram) atom of Hydrogen
Solution
H atoms are in 2 compounds, H₂O and HCl, so we calculate their mass in each compound
mass H in H₂O :[tex]\tt \dfrac{1}{36.5}\times 73=2~g[/tex]
mass H in HCl :
[tex]\tt \dfrac{2}{18}\times 144=16~g[/tex]
total mass = 2 g+ 16 g = 18 g

How can you change a objects state of matter
Answers
Answer:
Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form. This energy is usually heat or thermal energy.
Explanation:
After burning your candle for a few hours you and your friend notice that it's mass has decreased. Your friend claims that the mass "disappeared". Why do you know he is wrong (Hint: it's a Scientific Law)? What actually happened to the mass? What form is that mass in now? What is this process called?
Answers
Answer:
The law of conversion of mass is a scientific law that says that mass or matter can not be created or destroyed like energy but changes its form in a different type of state. So, by the law of conversion of mass, you can say that mass is not disappeared but change in different forms of states of matter like gas, soot, or melted residues of candle and ash of thread.
Due to this, the mass of the solid or waxy state due to burning changes to gas released by burning and residue of wax that will be equal to the mass of the original mass.

What volume does 14.0 g of Hydrogen gas (Hz) take up at a temperature of 30°C and a pressure of 120 kPa?
Note: Use Ideal gas law. R=8.31 (kPa x L)/(mol x K)
Answers
Answer:
V = 146.87 L
Explanation:
Given data:
Mass of sample = 14.0 g
Pressure of sample = 120 kpa
Volume of gas = ?
Temperature of gas = 30°C
Solution:
Number of moles of gas:
Number of moles = mass/molar mass
Number of moles = 14.0 g/ 2 g/mol
Number of moles = 7 mol
Pressure of gas:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 8.31 KPa.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
30+273 = 303 K
by putting values,
120 KPa × V = 7 mol × 8.31 KPa.L/ mol.K × 303 K
V = 17625.51 KPa .L/ 120 KPa
V = 146.87 L

AAA
Ice

Which statement is correct? (5 points)
The gas particles in both containers have the same average kinetic energy because they have equal number of particles
The gas particles in both containers have the same average kinetic energy because they have the same volume
The average kinetic energy of the gas particles is greater in container A because it has a lower temperature
The average kinetic energy of the gas particles is greater in container 8 because its particles move faster
Od
Answers
Answer:
D. The average kinetic energy of the gas particles is greater in container B because its particles move faster.
Explanation:
Option D is the correct statement. From the excerpt, it can be seen that container B is being heated. The heat that is applied to container B will make the temperature of the gas to increase, thereby increasing the average kinetic energy. This will cause the gas molecules to mover faster and with force hitting the walls of the gas container. At this time, pressure should increase. Also, the volume of the gas increases just as the temperature of the gas also increases.
Answer:
D. The average kinetic energy of the gas particles is greater in container B because its particles move faster.

Why do leavening gases expand faster at higher altitudes
Answers
Answer:
Cakes, breads and other foods that contain leavening agents rise more quickly at higher altitudes, because gases produced by the agents expand faster than at sea level. The loaves may collapse if the gases dissipate before the proper temperature is reached. Most baking recipes can be adjusted for high altitudes.
