In nature, hot air tends to rise and cool air tends to sink. This is behind the concept of convection heating that is used in ovens. Convection currents occur only in fluids such as liquids and gases but not in solids.

Which of the examples below is an example of convection?
A) rubbing your hands together.
B) heating a fish tank.
C) basking in the sun.
D) striking a match.

Explanation:

MODES OF HEAT TRANSFER

1) Conduction: This type of heat transfer happens when there is direct contact between the two object.

2) Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

3) Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

A. Rubbing your hands together, is a type of energy transformation in which mechanical energy transforms to heat energy.

C. Basking in the sun: is a type of radiation as the sun energy is transferred through space.

D. Striking a match: is a energy transformation in which mechanical energy transforms to heat and light energy.
