Question

during which of the following processes is there a decrease in the heat content of the form of water indicated? a rain water droplets as they fall to the ground b water as it evaporates from a pond c snow as it melts on a mountainside d ice as it forms on a lake

Explanation:

When ice forms on a lake, water changes from the liquid to the solid - state (freezing). Freezing is an exothermic process, meaning heat is released from the water, thus decreasing its heat content. Rain - water droplets falling to the ground may gain or lose heat depending on the environment but it's not a process that inherently decreases heat content. Evaporation of water from a pond and melting of snow are endothermic processes where heat is absorbed.

Answer:

D. Ice as it forms on a lake
