Laws of Thermodynamics Flashcard

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids or gases) where warm molecules rise and cool molecules sink.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through empty space without the need for a medium.

Front

What is thermodynamics?

Back

Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.

Front

What does the Zeroth Law of Thermodynamics state?

Back

If two bodies are in thermal equilibrium with a third body, they are also in equilibrium with each other.

Front

What is heat?

Back

Heat is energy transferred between substances or systems due to a temperature difference.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is the First Law of Thermodynamics?

Back

The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the Second Law of Thermodynamics?

Back

The Second Law of Thermodynamics states that the total entropy of an isolated system can never decrease over time.

Front

What is entropy?

Back

Entropy is a measure of the disorder or randomness in a system.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two bodies in contact do not exchange heat because they are at the same temperature.
