Asked by Meg
My teacher provided info about a worksheet of problems.
Special Heat of water: 4.184
Special Heat of Steam: 2.09
Special Heat of Ice: 1.8
Based on this info, and the notes we have taken on phase changes, we are supposed to find out how much energy is needed to change certain substances.
I thought, however, that in order to create a phase change, one must use the q=m,delta,Hfusion or m,delta,Hvap. How can I perform these equations without the Hvap/fusion info provided?!
Question 4, for example asks...
...60g of water at 43 degrees celcius to steam at 140 degrees celcius.
Help please?!?!?
