The latent heat of vaporization of water is 540 calories/gram. how many calories are required to completely vaporize 500 grams of water? 1,040 cal 40 cal 270,000 cal 1.08 cal

270,000 cal

Explanation:

In order to calculate the calories needed to completely vaporize 500 grams of water we just have to use the formula of the latent heat of vaporization, we know that it takes 540 calories to vaporize a gram of water, so we just multiply that by the number of grams:

(500 grams of water)(540 calories/gram)= 270,000 calories

It would taje 270,000 calories to vaporize 500 grams of water.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
