Heat Transfer Concepts

Front

What is conduction?

Back

Conduction is the transfer of heat 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 heat through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink, 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 from the sun to reach the Earth.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold an object is, typically measured in degrees Celsius, Kelvin, or Fahrenheit.

Front

What happens during thermal equilibrium?

Back

When two objects at different temperatures come into contact, heat will flow from the hotter object to the cooler one until they reach the same temperature.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

Front

How does heat transfer affect weather patterns?

Back

Heat transfer through convection in the atmosphere helps create wind and weather patterns, influencing climate and temperature changes.
