Heat Transfer

A bigger pot of water has more energy than a smaller pot of water. Why is that?

• The larger pot has more area to heat up on the stove.

• The smaller pot doesn't get as hot on the stove.

• There are more molecules or particles in motion in the big pot than in the smaller pot.

• Both pots actually have the same amount of energy.
