Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, which depends on both the temperature and the number of particles.

Front

How does the number of particles affect thermal energy?

Back

The more particles an object has, the more thermal energy it contains, even if the temperature is the same.

Front

What is the difference between temperature and thermal energy?

Back

Temperature measures the average kinetic energy of particles, while thermal energy measures the total kinetic energy of all particles in an object.

Front

What happens to thermal energy when heat is transferred?

Back

When heat is transferred, thermal energy moves from a hotter object to a cooler one until they reach the same temperature.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. The faster the particles move, the more kinetic energy they have.

Front

What is the relationship between temperature and kinetic energy?

Back

As the temperature of an object increases, the average kinetic energy of its particles also increases.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is the principle of heat transfer?

Back

Heat transfer occurs from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat, meaning they are at the same temperature.
