How do the molecules differ in a cup of hot water and a cup of cold water?

Question

answers below:
In the hot water, the molecules are moving faster than in the cold water.

In the cold water, the molecules are moving faster than in the hot water.

In the hot water, there are more molecules.

In the cold water, there are more molecules.

Answer 1

The correct answer is: In the hot water, the molecules are moving faster than in the cold water.

In hot water, the increased temperature provides more energy to the water molecules, causing them to move more rapidly. In contrast, in cold water, the molecules have less energy and move more slowly. The number of molecules in each cup can vary based on the volume of water, but the key difference related to temperature is the speed of molecular movement.
