Conduction, Convection & Radiation Practice

Front

What is convection?

Back

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

How does heat transfer occur in the ocean?

Back

Heat transfer in the ocean occurs primarily through convection, where warm water rises and cool water sinks, creating ocean currents.

Front

Which heats and cools faster: land, sea, or air?

Back

Land heats and cools faster than both sea and air due to its lower specific heat capacity.

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.

How does an iron smooth out wrinkles in clothes?

Back

An iron smooths out wrinkles by transferring heat to the clothes through conduction.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation from the sun.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising near a heater, causing cooler air to move in and create a circulation of air.

Front

What role does density play in convection?

Back

In convection, warmer fluids are less dense and rise, while cooler fluids are denser and sink, creating a cycle of movement.

Front

What is the primary method of heat transfer in liquids?

Back

The primary method of heat transfer in liquids is convection.

How does heat escape from a hot cup of coffee?

Back

Heat escapes from a hot cup of coffee primarily through convection and radiation.
