Front

What is thermal energy transfer by convection?

Back

Thermal energy transfer through the movement of fluids (liquids or gases) where warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state, such as a wound spring in a wind-up toy.

Front

What happens to the temperature of water in insulated cups connected by a conductor over time?

Back

The temperature in the hotter cup will decrease while the temperature in the cooler cup will increase as heat flows from hot to cold.

Front

What is the sequence of energy conversion in a gasoline-powered generator?

Back

Chemical energy from gasoline is converted to mechanical energy, then to electrical energy, and finally to radiant energy (light).

Front

What is a renewable source of electrical energy?

Back

A source of energy that can be replenished naturally, such as biomass, solar, wind, or hydroelectric power.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources (e.g., coal, oil) are finite and will deplete over time.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion, which increases with speed and mass.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of thermal energy transfer in everyday life?

Back

Boiling water in a pot on the stove, where heat from the burner transfers to the pot and then to the water.
