Question

Quizplus · Accepted Answer

The heat required to convert water at its boiling point to steam is known as the latent heat of vaporization, which is 540 calories per gram. Therefore, for 50 grams, it would be 50 x 540 = 27,000 calories. This is more than the heat required to bring 50 grams of ice from absolute zero to the boiling point.
