FLASHCARD 3- TASK LIST 3 QUIZ

Front

What happens to the average kinetic energy of particles in a substance as its temperature increases?

Back

The average kinetic energy of its particles increases.

Front

Define convection.

Back

The transfer of thermal energy in a fluid (liquid/gas) by movement of warm/cool fluids.

Front

How do particles in a substance move when it is heated?

Back

They move more quickly.

Front

What type of heat transfer is demonstrated when warm air rises and cool air sinks?

Back

Convection.

Front

Which of the following is not a method for heat transfer: Radiation, Insulation, Conduction, Convection?

Back

Insulation.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is radiation in terms of heat transfer?

Back

The transfer of heat through electromagnetic waves.

Front

What is the role of thermal energy in heating substances?

Back

Thermal energy causes particles to move faster, increasing temperature.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is through fluid movement.

Front

What is an example of convection in everyday life?

Back

Boiling water, where hot water rises and cool water sinks.
