60s - Q14
A jar of water is placed over a flame and the flame warms the water at the bottom of the jar.
As the water at the bottom of the jar becomes a little warmer than the water around it, the warmer water will start to rise.
The water at the bottom of the jar will get warmer, but it will not rise.
The water at the bottom of the jar will get warmer and warmer, but it will not rise until it starts to boil.
