Question

What5 mass of water at 100c can be vaporized by the addition of 45 kcal of heat?

Answer 1

Answer: -

83.3 g of water can be vaporized by the addition of 45 kcal of heat at 100° C

Explanation: -

Heat of vaporization = 540 Cal / g.

Heat supplied = Q = 45 Kcal = 45 x 1000 Cal

Mass of water= Heat supplied / Heat of vaporization

= 45 x 1000 Cal / (540 Cal /g)

= 83.3 g
