(b) Two containers made of Insulating material contain the same volume of water at roorh temperature. The containers do not have lids. The volume of liquid in each container graduall- decreases.

(i) After a certain time, the temperature of the water has decreased to below room

temperature.

Explain, in terms of molecules, why the temperature has decreased.

(ii) One of the containers is wide and shallow. The other container is narrow and deep.

Predict which container has the greater rate of cooling. Explain your answer.​

See Explanation

Explanation:

Evaporation is an endothermic process, an endothermic process is one in which energy is absorbed from the surrounding thereby making the system to be at a lower temperature compared to the environment.

Being an exothermic process, molecules take away energy from the liquid surface as they escape from the liquid surface hence, evaporation causes the temperature of the water to be decreased below room temperature.

The rate of evaporation and cooling depends on the surface area of liquid. The liquid in the wide and shallow container has a greater rate of cooling because it has a greater surface area than the liquid in the narrow and deep container.

the answer is 1 i believe
