heat to raise temp

Postby 705121606 » Mon Jan 27, 2020 4:42 pm

In problem 4A7b it asks what percentage of heat is used to raise the temperature of water. We are also told to specific heat and molar capacities. I wanted to know what the equation was to solve this question

There is not really a singular equation you would use to solve this part b) of this question. Once you have calculated the heat necessary to raise the temperature of water and the heat needed to raise the temperature of the entire solution, you can just divide the heat transferred to water by the total heat transferred to the system, then multiply this by 100 percent. This is the same principle as calculating percent ionization: (final/desired value) / initial value x 100%. If you don't multiply by 100 you can't convert your value to a percentage.

how do we calculate the heat necessary to raise the temperature of water
