Question

How many joules of energy are required to vaporize 423 grams of water at 100 degrees Celsius and 1 atm?

Answer 1

Answer:

955980 j

Explanation:

Given data:

Mass of water = 423 g

Temperature = 100°C

Amount of energy required = ?

Solution:

For one gram of water heat of energy required to convert it into vapors is 2260 j/g.

Amount of heat required for 423 g.

423 g × 2260 j/g = 955980 j

The amount of energy released when one gram steam is condensed into water is -2260 j.

For 423 g water vapor to condensed energy released.

423 g × -2260 j/g = -955980 j
