Question

(a) Two identical open boxes originally contain the same volume of water. One is kept at 15°C and the other at 85°C for the same length of time.
Fig. 4.1 shows the final water levels.


With reference to the energies of the water molecules, explain why the levels are different.​

Answer 1

Explanation:

because as you can see beaker 2 has higher temperature. As volume is directly propotional

to temperature. So the the water molecules has

more energy so that's why levels are different.
