Sublimation needs heat to work.

Detailed Description

Can't sublimate without the heat

Without the addition of energy (heat) to the process, ice would not sublimate into vapor. That is where sunlight plays a large role in the natural world. Water has a physical property called the "heat of vaporization," which is the amount of heat required to vaporize water.
