Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

What is convection?

Back

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

Front

In which direction does thermal energy flow?

Back

Thermal energy always flows from a warmer area to a cooler area.

Front

What causes the Earth to have seasons?

Back

The Earth has seasons because it is tilted on its axis as it revolves around the sun, leading to varying angles of sunlight at different times of the year.

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 transfer of thermal energy between them.

Front

How does temperature affect thermal energy transfer?

Back

The greater the temperature difference between two objects, the faster the rate of thermal energy transfer between them.

Front

What is the role of the sun in heating the Earth?

Back

The sun provides thermal energy to the Earth through radiation, warming the surface and influencing weather patterns and climate.

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.
