Exothermic reaction releases heat to the surroundings. Endothermic reaction absorbs heat from the surroundings. Condensation of water is an exothermic process. Evaporation of water is an endothermic process. Which option explains best why spraying water on the drive way on a hot summer day makes us feel cool? a. During the evaporation of the sprayed water on the drive way on a hot day, heat is supplied to the air surrounding the sprayed water. From the perspective of the surroundings, the air loses heat to the evaporation process. Thus the air temperature drops down and thus we feel cool.
b. During the evaporation of the sprayed water on the drive way on a hot day, heat is supplied from the air surrounding the sprayed water. From the perspective of the sprayed water, it loses heat to the air during the evaporation process. Thus the air temperature drops down and thus we feel cool.
c. During the evaporation of the sprayed water on the drive way on a hot day, heat is supplied from the air surrounding the sprayed water. From the perspective of the sprayed water, it loses heat to the water itself during the evaporation process. Thus the air temperature drops down and thus we feel cool.
d. During the evaporation of the sprayed water on the drive way on a hot day, heat is supplied from the air surrounding the sprayed water. From the perspective of the surroundings, the air loses heat to the evaporation process. Thus the air temperature drops down and thus we feel cool.
