Monique heats a pan of water on the stove. The lid rattles and steam escapes.
What could account for this?
(1 point)
The water molecules have lost kinetic energy and increased in volume.
The pan lid has increased in volume and no longer fits the pan.
The molecules of water have gained kinetic energy and increased in volume.
The temperature of the water has increased, but the kinetic energy of the water molecules has decreased.
I think C or D.

The correct answer is C. The molecules of water have gained kinetic energy and increased in volume. As the water is heated, the molecules gain kinetic energy and move faster, which causes them to spread out and increase in volume. This increase in volume creates pressure, which causes the lid to rattle and steam to escape.
Answers for the Potential and Kinetic Energy Quick Check !!
1: Potential energy
2: after it goes downhill and begins to climb again
3: He can use a thermometer to measure the water's temperature.
4: Gas A has greater kinetic energy.
5: The molecules of water have gained kinetic energy and increased in volume.
hope this helps !!
