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.

ugh fiel iente of insistí is did kiwis jaj

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
