Energy Transfer and Temperature

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 motion.

Front

How does energy transfer occur in a hockey game?

Back

Energy is transferred from the player to the puck when the player hits it with the stick.

Front

What happens when you touch a hot stove?

Back

Heat energy transfers from the stove to your hand, causing a sensation of heat.

Front

What factors affect the amount of heat required to raise the temperature of a substance?

Back

The nature of the matter (its specific heat capacity) and its mass affect the amount of heat required.

Front

Define mass in the context of energy transfer.

Back

Mass is the amount of matter in an object, which influences how much energy is needed to change its temperature.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

Explain the concept of specific heat capacity.

Back

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is conduction?

Back

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

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

What is radiation?

Back

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