Thermal Physics Flashcards
What is specific latent heat?
The amount of energy required to change the state of a 1kg substance without a change in temperature.
What is the pressure law?
The pressure of an ideal gas is directly proportional to its absolute temperature, when the volume is fixed.
What is Boyle’s Law?
The pressure of an ideal gas is inversely proportional to its volume when held at a constant temperature.
What is Charles’ Law?
The volume of an ideal gas is directly proportional to its absolute temperature when held at a constant pressure.
What is internal energy?
The sum of the randomly distributed kinetic and potential energies of the particles in a given system.
What is the Boltzmann Constant?
A constant relating the average kinetic energy of the particles in a gas to the gas’ temperature.
What is the Avagadro Constant?
The number of particles that make up one mole of any gas.
What is the Molar Gas Constant?
A fundamental constant, used in the ideal gas laws.
What is Brownian motion?
The random motion of particles.
What is specific heat capacity?
The amount of energy required to increase the temperature of 1kg of a substance by 1 Kelvin.
What is the molecular mass?
The mass of one mole of the substance in question.
What is molar mass?
The mass of one mole of the substance in question.
What is an ideal gas?
A gas that meets the ideal gas assumptions. All the gas laws are based on ideal gases.
What is absolute zero?
The lowest possible temperature of a system, where no heat remains and the particles in the system have no kinetic energy.
What is the Kelvin scale?
An absolute temperature scale that starts at absolute zero. (0K=-273°C)
