Asample of water is being heated over a flame. what happens to the water as it is heated? (2 points)
the velocity of the water molecules begins to decrease.
the volume of the water decreases.
the water undergoes an endothermic reaction.
the kinetic energy of the water molecules increases.

The answer is D, the kinetic energy of the water molecules begins to increase. When you heat up a pot of water, the water molecules begin to move very fast. Thus, stating that the kinetic energy of water molecules increase since the water molecules go from moving a little bit to moving really fast! I hope this could help!

You know how the first one if filled up like the objects do the same but with the other categories

about what?
have a good day
