Thermal energy is the total energy of all the particles in an object due to their motion. It is related to temperature and heat.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is, usually measured in degrees Celsius (°C) or Fahrenheit (°F).

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What is the freezing point of water in Celsius?

Back

The freezing point of water is 0°C.

Front

What is the boiling point of water in Celsius?

Back

The boiling point of water is 100°C.

Front

What is the definition of 'average temperature'?

Back

Average temperature is calculated by adding all temperature readings and dividing by the number of readings.
