Keeping the molecule in a low temperature. The temperature varies on what type of molecule.

The waxy transparent layer of leaves prevents water evaporation.
Opening/closing of leaf pores (stoma) has the purpose to control evaporation.
The plastic wrap that prevents evaporation the best is Saran wrap. Reynolds's Plastic wrap works for the prevention of evaporation also.
Factors that prevent excess evaporation of water include high humidity levels in the air, the presence of a water-impermeable covering (such as mulch or dense vegetation) on the soil surface, and cooler temperatures that reduce evaporation rates. Additionally, windbreaks or structures can help reduce wind exposure, which can increase evaporation.
Water evaporation from a pool with a cover on is greatly reduced compared to a pool without a cover. The cover helps to create a barrier that prevents evaporation caused by wind and sunlight. The reduction in evaporation can be as much as 90% with a cover on.
The waxy surface on a leaf is called the cuticle. It is a waterproof layer that helps reduce water loss through evaporation, while also offering protection against pathogens and pests.
Assuming you mean in plant life, it prevents dehydration through evaporation
On, it does not stop the sun from heating the water, it holds the heat in though. ( evaporation cools it quickly and the cover prevents this )
