Question

A sample of water is heated from 10.0 degrees Celcius to 15.0 degrees Celcius by the addition of 125 Joules of heat. What is the mass of the water?

Answer 1

125 = 5*4.186*m

m = 125 / 5*4.186 = 5.97g of water.

Step-by-step explanation:

The water is increased by 5 degrees. This means that for every gram of water, it takes 5*4.186 J to increase the temperature by 5 degrees, aka 5*4.186 J/g
