Question

Finishing his ginger ale, Ramesh stands at the party holding his insulated foam cup that has nothing in it but 0.100kg of ice at 0 degree celsius. How much heat must be gained by the ice in order for all of it to melt? How much more heat must be gained to raise the temperature of the melted ice to room temperature of 23.0 celsius?

First question I have it: 3.35 x 10^4J
but second I don't know how to do it. Please, could you help me??? Thank you so much

Answer 1

Your answer to the first question is correct. For part 2, you need to used the specific heat C, the mass M, and the temperature rise (delta T = 23 C)

The specific heat of water is
C = 4.184 J/(deg*gram)

Q = M*C*(delta T) = 100*4.184*23 = ___ J

Answer 2

9623.2 J

Answer 3

How did you get the first answer?
