Thermal Energy & Transforming Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is the principle of energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is radiation in terms of energy transfer?

Back

Radiation is the transfer of energy through electromagnetic waves, such as feeling warmth from the sun.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

Front

How does insulation work?

Back

Insulation slows down the transfer of thermal energy, helping to keep homes warm by trapping air, which is a poor conductor of heat.

Front

What happens to energy when a flashlight is turned on?

Back

The battery's chemical energy is transformed into electrical energy, which is then converted into light energy and thermal energy.

Front

What is convection?

Back

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

Front

How does heating air in a hot-air balloon affect its density?

Back

Heating air inside a hot-air balloon causes the air particles to move faster and spread apart, decreasing the air's density and allowing the balloon to rise.

Front

What is the law of conservation of energy?

Back

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