Thermal Energy, Temperature and Heat

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature.

Front

What is temperature?

Back

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

Front

What is heat?

Back

Heat is the transfer of thermal energy from a warmer object to a cooler object.

Front

What is absolute zero?

Back

Absolute zero is the lowest possible temperature, 0 Kelvin, where all molecular motion stops.

Front

What is the Celsius scale?

Back

The Celsius scale is a temperature scale where 0°C is the freezing point of water and 100°C is the boiling point.

Front

What is the Fahrenheit scale?

Back

The Fahrenheit scale is a temperature scale where 32°F is the freezing point of water and 212°F is the boiling point.

Front

What is the Kelvin scale?

Back

The Kelvin scale is an absolute temperature scale used in science, where 0 K is absolute zero.

Front

How does heat transfer occur?

Back

Heat transfer occurs only from warm objects to colder ones.

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).
