) In the calculation set-up below to determine how much heat is needed to convert 50 g of ice at ?20 °C to steam at 300 °C, which constant does C represent?
(A)(50 g)(20 °C) + (heat of fusion)(50 g) + (B)(50 g)(100 °C) + (heat of vap.)(50 g) + (C)(50 g)(200 °C) = total heat

Question

Quizplus · Accepted Answer

C represents the specific heat of steam, which is the amount of heat needed to raise the temperature of a unit mass of steam by one degree Celsius. This is used in the last term of the equation to calculate the heat needed to raise the temperature of steam from 100 °C to 300 °C.
