Thermal Energy

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What are good insulators?

Back

Good insulators are materials that do not conduct heat well, such as wood, rubber, and plastic.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily, such as metals like copper and aluminum.

Front

How does temperature affect thermal energy?

Back

As temperature increases, the thermal energy of a substance also increases due to the greater motion of its particles.

Front

What is the difference between heat and temperature?

Back

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

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
