Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

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

Front

Why is metal a good conductor of heat?

Back

Metal is a good conductor of heat because it has free electrons that can move easily, allowing heat to be transferred quickly from one part of the metal to another.

Front

What happens to air density when it is heated?

Back

Warm air is less dense than cold air, causing it to rise.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises from a heater, creating a circulation of warm air in a room.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium to transfer heat, while conduction and convection require direct contact or fluid movement, respectively.

Front

What is an example of radiation?

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 role does convection play in weather patterns?

Back

Convection helps to distribute heat in the atmosphere, leading to the formation of clouds and weather systems.

Front

What is the relationship between temperature and density in fluids?

Back

As temperature increases, the density of fluids generally decreases, causing warmer fluids to rise.
