Kinetic Energy and Heat Transfer Concepts

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Thermal Energy?

Back

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

Front

What is Conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is Convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is Radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

How does thermal energy transfer from a stove to a pan?

Back

Thermal energy transfers from the stove to the pan through conduction.

Front

What happens to thermal energy when ice is placed in a warm drink?

Back

The thermal energy transfers from the warm drink (coke) to the ice until both reach the same temperature.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by four times.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks to the bottom.
