We use electrical devices that produce motion, light, and sound. which aspect of energy explains why these devices are possible?

For this question look at the hydropic diagram water that is heated by the sun evaporates. select the number that represents it.

The energy required to vaporize a certain amount of a substance is greater than the amount of energy necessary to raise the temperature of the same amout of that substance by 1 degreee celcius
