Considering the two samples of water above (one is 100. g, the other 25.0 g) both at the same initial temperature of 25.0 degrees Celsius, the final temperature of the 25.0 g sample was 73.0 degrees Celsius. What is the final temperature of the sample of water weighing 100. g? Answer.

The final temperature of the 100 g sample of water is 37.0 degrees Celsius. Since the higher mass sample is four times greater than the lower mass sample, and knowing the inverse relationship between the temperature change and the mass we would predict the temperature change to be one-fourth that of the sample with the smaller mass. So the 100 g sample will undergo a temperature change of 12 degrees, or a fourth of the temperature change of the 25.0 g sample of water and the final temperature is 37.0 degrees Celsius.
