What happens to warm air in convection?

Back

Warm air rises because it is less dense than cool air, which sinks.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

Which state of matter is generally the most dense?

Back

Solids are generally the most dense state of matter.

Front

What is an example of conduction?

Back

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