A substance is considered more efficient at storing energy when its specific heat enables it to resist changes in temperature. s
joja [24]

Water stores energy more efficiently than air under equal conditions.

It requires more energy to heat water than it does to heat air because water has a significantly larger heat capacity and specific heat than air. Compared to air, which has a specific heat of 1.005 J/g degreesC, water has a specific heat of 4.186 J/g degreesC.

Specific heat:

The amount of heat required to raise the temperature per unit mass is known as specific heat capacity. The heat in Joules required to increase the temperature of 1 gram of sample by 1 Kelvin or degree Celsius is often stated. Water is an excellent temperature regulator since it has a very high specific heat capacity.
