6a. Thermal Physics Flashcards
Specific heat capacity
The energy required to raise a unit mass of a substance by 1 degree kelvin.
Specific latent heat of vaporization
The energy required to convert a unit mass of a substance from a liquid state to a gaseous state without change in temperature.
Boyles Law
The pressure of an ideal gas is inversely proportional to the volume so long as the temperature remains constant.
Charles Law
The absolute temperature of an ideal gas is directly proportional to its volume so long as the pressure remains constant.
The pressure law
The absolute temperature of a gas is directly proportional to the pressure so long as the volume remains constant.
Avogadro’s law
Equal volumes of different gases at the same temperature and pressure will contain the same number of particles of gas.
Absolute zero
Where a gas has zero volume, pressure, temperature and internal energy.
The assumptions of the ideal gas
a) All particles are identical
b) All energy is kinetic
c) The particles volume is very small in comparison with the distance between the particles
d) All collisions are elastic
e) Particles move in straight lines
f) The motion of particles is random with no preferred direction
