You add 1500 cal of heat to a cup of water at 22.5ºC. The water has a mass of 500.0g. What is the final temperature of the water?
The Attempt at a Solution
so i tried solving it by finding the energy of the water
then i tried adding 11250 cals to the 1500 cals that was added onto it from the problem and got 12750 cals.
using 12750 cals as Q, i set up Q=mcΔT and plugged in all the known variables and solved for change in T, which was 25.5ºC. I took this change in T and added it to the initial temperature of 22.5ºC, and got 48ºC for the final temperature of the water. Is that right? I didn't get an answer sheet and I have a test tomorrow so I have no idea if I'm doing this right or not
