If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
What is the First Law of Thermodynamics?
Energy cannot be created nor destroyed, only transferred or converted from one form to another.
What is the Second Law of Thermodynamics?
The entropy of an isolated system will always increase over time, approaching a maximum value at equilibrium.
What is the Third Law of Thermodynamics?
It is impossible to reach absolute zero through any finite number of processes.
What is thermal equilibrium?
The state in which two systems in contact with each other exchange no heat energy because they are at the same temperature.
What is the formula for the First Law of Thermodynamics?
ΔU = Q - W
What is the symbol for entropy?
S
What is absolute zero?
The temperature at which all matter reaches its minimum possible energy state, approximately -273.15°C or 0K.
What is the Carnot cycle?
A theoretical heat engine that operates on the reversible Carnot cycle, the most efficient cycle possible in terms of converting heat energy into work.
What is the principle of conservation of energy?
Energy cannot be created nor destroyed; the total amount of energy in a system remains constant.
What is the definition of entropy?
The degree of disorder or randomness in a system.
What is the Kelvin-Planck statement of the Second Law of Thermodynamics?
No heat engine can have a higher efficiency than a Carnot engine operating between the same high temperature and low temperature reservoirs.
Work is done when a force acts on a system and moves it through a distance.
What is the definition of heat in thermodynamics?
Heat is the transfer of energy from a higher-temperature object to a lower-temperature object.
What is the Zeroth Law of Thermodynamics?
If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
