TASK LIST # 3 Practice (24)

Front

What is conduction?

Back

Conduction is the transfer of heat energy through direct contact between materials. It occurs when faster-moving particles collide with slower-moving particles, transferring energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat energy through electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

How does thermal energy relate to the amount of matter in an object?

Back

The more matter or particles an object has, the more thermal energy it possesses, as thermal energy is related to the motion of particles.

Front

What happens to heat energy when a hot object is placed in a cooler environment?

Back

Heat energy will transfer from the hot object to the cooler environment until thermal equilibrium is reached.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

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.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer between objects by minimizing conduction, convection, and radiation.
