* Water's High Specific Heat Capacity: Water has a very high specific heat capacity. This means it takes a lot of energy to raise the temperature of water compared to other substances like soil. When water is present in soil, it absorbs a significant amount of heat energy, which helps the soil retain that heat for longer.

* Evaporation: When water evaporates from wet soil, it takes a significant amount of heat energy with it (latent heat of vaporization). This further cools the soil. Dry soil doesn't have this cooling effect.

* Thermal Conductivity: Wet soil has higher thermal conductivity than dry soil. This means heat can transfer through it more easily. In a wet environment, the heat can be distributed more evenly, making the soil feel cooler.

In summary:

Wet soil is able to absorb more heat than dry soil due to water's high specific heat capacity, the cooling effect of evaporation, and its higher thermal conductivity.
