If 10 calories of heat are added to two grams of liquid water what is the temperature of the water
If you don't know the temperature at the start you can't know the final T; however, you can calculate delta T.
q = m*c*delta T
10 = 2 x 1 x dT. Solve for delta T. I get T will be 5 degrees C warmer than where it started.
