Question

Which hold more heat for longer period of time ?

A. Air
B. Water

Answer 1

B. water

Step-by-step explanation:

Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. As a result, it takes water a long time to heat and a long time to cool.

Answer 2

water

Step-by-step explanation:

The heat capacity of a material, along with its total mass and its temperature, tell us how much thermal energy is stored in a material. ... The result is that the temperature of the water cube is much more stable than the air — the water changes much more slowly; it holds onto its temperature longer.
