Internal Energy and Temperature

A collection of flashcards summarizing key concepts about internal energy, temperature, and the process of evaporation.

Internal energy

The energy stored in the movement of particles; also known as thermal energy or heat energy.

Joules

The unit of measurement for energy.

Temperature

A measure of how hot or cold an object is, typically measured in degrees Celsius (°C).

Factors affecting internal energy

Internal energy depends on temperature, the material from which it is made, and its mass.

Energy flow

Energy flows from a hotter object to a cooler object until they reach the same temperature.

Evaporation

The process of turning liquid into vapor, which is also a way of transferring energy.

Boiling point

The temperature at which a liquid evaporates fastest, which is 100°C for water.

Sweat evaporation

The process of sweat turning from liquid to gas, cooling the skin and underlying tissues.
