Energy Transfer Practice

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, often resulting in a change in temperature or state.

Front

What happens to the temperature of an object when it absorbs energy?

Back

The temperature of the object increases when it absorbs energy.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

How does color affect energy absorption?

Back

Darker colors absorb more light and energy, while lighter colors reflect more light and energy.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the role of air in heat transfer?

Back

Air can transfer heat through convection, but it is a poor conductor of heat compared to solids.

Front

What is the effect of temperature on the state of matter?

Back

Increasing temperature can cause solids to melt into liquids and liquids to evaporate into gases.

What is the principle of heat transfer in ice melting on a sidewalk?

Back

Heat energy flows from the warmer sidewalk to the cooler ice, causing the ice to melt.
