Question 10

A jar of water is placed over a flame and the flame warms the water at the bottom of the jar.

What happens to the water at the bottom of the jar before it boils?

Accepted Answer

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.

Answer

The water at the bottom of the jar will get warmer, but it will not rise.

Answer

All of the water in the jar will get warmer at the same time, so there is no movement of the water in the jar.
