The surface of water in a pond remains cool even on a hot day because

Q.

Statement 1: Evaporation causes cooling of the liquid

Statement 2: During evaporation, the surface molecules with high kinetic energy get evaporated.

Q. Assertion :A desert cooler cools better on a hot dry day. Reason: On a hot dry day, the temperature is high and humidity is low. The water takes heat from the hot desert cooler and evaporates. The evaporation of water cools the pads and the circulating water.

Q. Why is water in an open pond cool even on a hot day?

Q. An air bubble is rising up from the bottom of a pond. Find the depth of the pond, if its volume at the surface becomes eight times its volume at the bottom. Find the depth of the pond. (Write your answer to the nearest integer)

Q. A standard, ground-based evaporation pan, corresponding to Indian Standards, is installed at the banks of a surface reservoir. The water surface area on a particular day is 100 hectares. The recorded evaporation loss from the pan, on a certain day, is nearly 4.0 cm. What is the anticipated evaporation loss from the reservoir for that day?
