I have an Earth Science question that I need help with ..
1,500 calories of heat are added to a 30 gram sample of liquid water. If the water sample started at 25 degrees C, what will the final temperature be ?

you need to use the specific heat of water to solve this. The specific heat tells us the amount of energy (calories) needed to raise the temperature of 1 gm of a substance 1 degree. Using this information you can easily solve the problem.

This question is a prime example of why we should/must get rid of that silly, foreign system of measurement. Keep it in American standard where one British Thermal Unit is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit and it is so much easier to calculate and understand!!!
