Thermal Energy

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. An example is heat moving from a clothes iron to a shirt.

Front

Which material is the best conductor of heat?

Back

Metal is the best conductor of heat.

Front

What is the flow of thermal energy from warmer objects to cooler objects called?

Back

Heat.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is.

Front

How do the particles of a gas move compared to the particles of the same substance in liquid or solid state?

Back

The particles of a gas move faster than the particles of the same substance in the liquid or solid state.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, related to its temperature.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) due to differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight warming the Earth.

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 particles in a substance.

Front

What happens to the thermal energy of a substance when it is heated?

Back

When a substance is heated, its thermal energy increases, causing its particles to move faster.
