Steam Condensation (Thermo)
hi guys, i have the following question to answer:
a 40g copper calorimeter contains 200g of water at 20 degrees celsius, it asks how much stam must be condensed in order to achieve a final temperature of 50 degrees celsius.
I was just wondering what formula to use?, and do i need to know the specific heat of copper?

Yes, using the specific heat of copper and water, calculate how much heat is gained as the temperature rises from 20 to 50C. The equation for the calorimeter is simply heat gain equals specific heat times delta-T. For condesing steam, you have two parts: the heat loss from condensing the steam and the heat loss from cooling it from 100C to 50C.
