The latent heat of vaporization of water is 540 calories/gram. How many calories are required to completely vaporize 500 grams of water?

Answer 1

1 g = 540 calories
500 g = ? calories

Since the mass is 500 times 1 g, so the number of calories
= 500*540 calories

Answer 2

And thank you. (:

Answer 3

wah

Answer 4

it is 270000

Answer 5

It is not called a PROPORTION
It is called a MULTIPLICATION

Answer 6

Given,
heat of vaporization of water is 540 cal per gram
therefore amount of heat required
( 500 × 540) cal
is equal to 270000 calories...
