Assuming that you mean molecules present on the dermal surface with ''skin molecules'': they don't ''pop off'' when the adhesive force of the droplet to the skin surface is stronger than the kinetic energy; if the momentum caused by movement is high enough droplets will be displaced or get ''flung into space''.

But if a person spends too much time in the heat without taking in enough fluids, the body's cooling processes can't work properly. When the brains temperature regulation center receives data from the sensors indicating that the bodys temperature exceeds its normal range, it stimulates a cluster of brain cells referred to as the heat-loss center. This stimulation has three major effects: In contrast, activation of the brains heat-gain center by exposure to cold reduces blood flow to the skin, and blood returning from the limbs is diverted into a network of deep veins (Figure 2). 8 Jun 2023. https://askabiologist.asu.edu/bird-hypothalamus. are like most of us, your body probably sweats when it is warm, when your environment is warm, and you probably realize that it sweats in order to cool itself, in order to keep the So let's say that this is one that has evaporated, it has fully escaped.
