how to do part a, trial 1

Data Analysis Part A. 1. Calculate the specific heat for your metal for each trial. Remember that the heat lost by the metal is equal to the heat gained by the water in the calorimeter and by the calorimeter itself. This can be expressed as – metal (water + Jealorimeter). The specific heats are positive numbers.
