Materials absorb heat if they are colder than their surrounding and give up heat if they are warmer. The temperature change is related to a property of the material call heat capacity. It is defined as the amount of heat needed to change the temperature of 1 gm of a material by 1 degree Kelvin. So it has units of energy/unit mass/unit temperature (Joules/(kg-K) for instance.) . Water has a heat capacity of 1 Joule/gm/K. Air, being a gas has a lower capacity meaning you can change the temperature of air using less energy than say water.

It means, it doesnt take much energy to heat up/cool down air. Water has a high thermal capacity, it takes a lot of eenergy to heat up. All materials have different heat capacities.
