The Physics of Thermal Physics

17 questions covering Thermal Physics from topics 3.1 to 3.3. Requires basic knowledge of the states of matter, the equations dictating the relationship between forces and pressure as well as energy transfers in bodies and finally of the changes in a gas under different conditions and the energy exchanges between gases.

?
An increase in the internal energy of a solid object represents...?
An increase in the particles kinetic and potential energy

What are the units of the thermal capacity (c) of a body?
Joules per Kelvin (J/K)
2 of 12
What are the units of the specific heat capacity (c) of a body?
Joules per Kelvin kilograms (J/KgK)
3 of 12
The specific latent heat of a material is...?
The energy taken per kilogram of material to change the state of that material without changing its temperature
4 of 12
The total internal energy (Q) of a liquid above the temperature of its melting point is equal to...? (Where m is it's mass, C and L are constants and ΔT is the change in temperature)
Q = mC(liquid)ΔT + mL(liquid) + mC(solid)ΔT
5 of 12
The Kinetic model of an ideal gas assumes that...?
The gas molecules are perfectly elastic, identical, spherical, extremely small and experience no forces when not colliding
6 of 12
The SI units of pressure (P) are...?
Newtons per meter squared (N/(m^2))
7 of 12
Increasing the temperature of a gas with a constant volume...?
Increases the kinetic energy of the molecules of the gas and increases the pressure.
8 of 12
Decreasing the temperature of a gas at constant pressure...?
Decreases the kinetic energy of the molecules of gas and decreases the volume of the gas
9 of 12
Decreasing the pressure of a gas at constant volume...?
Decreases the kinetic energy of the gas molecules and also the temperature of the gas
10 of 12
When a gas is compressed at a constant temperature...?
Work is done on the gas
11 of 12
When a gas expands with a constant temperature...?
Work is done by the gas
