Thermal Physics Flashcards
Define absolute zero
0 kelvin / -273° c. The lowest possible temperature of a system, where no heat remains and the particles in the system have no kinetic energy
What is Avogadros constant?
The number of particles that make up one mole of any gas
What is Boltzmanns constant?
A constant relating the average kinetic energy of the particles in a gas, to the gas’ temperature
What is boyles law?
The pressure of an ideal gas is inversely proportional to its volume, when held at a constant temperature
What is Brownian motion?
The random motion of particles
What is Charles’ law?
The volume of an ideal gas is directly proportional to the temperature, when held at a constant pressure
What is an ideal gas?
A gas that meets all the ideal gas assumptions. All the gas laws are based on ideal gases
Define the internal energy of a gas
The sum of the randomly distributed kinetic and potential energies of the particles in a given system
What is the Molar gas constant?
A fundamental constant, used In the ideal gas law
What is meant by molar mass?
The mass of one mole of the substance in question
What is meant by molecular mass?
The mass of one molecule of the substance in question
What is the pressure law?
The pressure of an ideal gas is directly proportional to the absolute temperature, when the volume is fixed
Define specific heat capacity
The amount of energy required to increase the temperature of 1kg of a substance by 1 degree ( kelvin or Celsius )
Define specific latent heat
The amount of energy required to change the state of 1kg of substance without a change in temperature
