thermodynamics

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids. Example: Touching a hot stove.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases). Example: Boiling water where hot water rises and cold water sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. Example: Feeling warmth from the sun.

Front

What is entropy?

Back

Entropy is a measure of the disorder or randomness in a system. Higher entropy means more disorder.

Front

Which state of matter has the highest entropy?

Back

Vapor (gas) has the highest entropy compared to solids and liquids.

Front

What is the second law of thermodynamics?

Back

The second law states that the total entropy of an isolated system can never decrease over time.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is a heat engine?

Back

A heat engine is a device that converts thermal energy into mechanical work, typically operating in a cyclic process.
