• A cup of hot tea has higher energy than a cup of ice water.

• A cup of ice water has higher energy than a cup of hot tea.

• A cup of room temperature water has a higher energy than the air in the room around it. 

What statement below best describes how water temperature increases when energy is added?

• When heated water molecules move faster and the temperature of the water increases.

• When heated water molecules move slower and the temperature of the water increases.

• When heated the water molecules stand still and the temperature of the water increases.
