Specific Latent heat of fusion is the amount of energy needed to change the state of 1kg of a substance from liquid to solid
Specific latent heat of vaporisation is the amount of energy needed to change that state of 1kg of a substance from gas to liquid
Ideal gas assumptions:
large number of molecules in rapid, random motion
all collisions are perfectly elastic
duration of collisions is negligible compared to the time between collisions happening
negligible intermolecular forces exist except during collisions
molecules occupy negligible volume compared to the volume of gas in container
pV = constant
p/T = constant
V/T = constant
Boyle's Law states that the volume of a fixed mass of gas is inversely proportional to the pressure exerted on it provided the temperature is constant
Brownian motion is the random movement of particles in a liquid or gas.
Internal energy is the total energy of the particles in a system, including the kinetic and potential energies.
Specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degree
Root mean square speed of the molecules in a gas is the square root of the average speed of the molecules and is used to find the pressure of a gas using the equation pV = 1/3Nm*root(c^2)
When a molecule collides with a wall elastically, the momentum changes from +mv to -mv so the total change in momentum is 2mv for one particle
Thermal conductivity is the ability of a material to transfer heat between two points
