(a) in an experiment, cold water is poured into a bowl made of an insulating material, the container

is placed in a draught-free room. After several hours, the volume and the temperature of the

water are found to have decreased.

Name and describe the process that causes the decrease in the volume of the water, and

explain why the temperature of the water decreases.

Evaporation and heat loss to the surrounding.

Explanation:

The process is known as evaporation.

Evaporation takes place at any temperature but increases with increase in temperature. The molecules of water evaporate, that is, escape into the atmosphere thereby causing the volume of water to reduce.

The temperature decreases due to heat loss from the water into the surrounding. This will cause the temperature of the water to drop.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

gravitational energy

electrical energy

kinetic energy

ligh energy
