What happens to ice cubes of different sizes when exposed to heat?

Back

Smaller ice cubes melt faster than larger ones due to a higher surface area to volume ratio.

Front

What is an example of convection in everyday life?

Back

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