Thermal Physics

Question 0

What is Charles’ Law?

Answer 0

Volume and temperature are proportional

When pressure is constant

Question 1

What is Boyle’s Law?

Answer 1

Pressure and volume are inversely proportional

When temperature is constant

Question 2

What is the pressure law?

Answer 2

Pressure and temperature are proportional

When Volume is constant

Question 3

What is an ideal gas?

Answer 3

A gas composed of moving, non-interacting point particles. The has obeys the ideal gas equation.

Question 4

What happens to particle speed as the temperature increases?

Answer 4

Average particle speed and maximum speed increase

Question 5

What is the specific heat capacity of a substance?

Answer 5

The amount of energy needed to raise the temperature of 1kg of the substance by 1 degree.

Question 6

What is the specific latent heat of fusion or vaporisation?

Answer 6

The amount of thermal energy needed to cause 1kg of a substance to change state.

Question 7

What are the energy changes in gas?

Answer 7

Particles will travel with different Ek’s and their Ek will change as a result of collisions. Between collisions they do not accelerate.
Total energy of gas is constant
So average speed will stay the same provided that the temperature is the same.
