2, the heat change of a sample of metal or water can be calculated from the mass, specific heat, and temperature change of the substance. This is indicated in Eq. 4 and Eq. 5. q metal = (mass of metal)(C p)(â T) (4) q water = (mass of water)(C p)(â T) (5) Substituting these equations into Eq.
Average is the number that is found by dividing the sum of data by the number of items in the data set.verage is the number that is found by dividing the sum of data by the number of items in the data set.
 The mean is the average of a given set of numbers. You add the numbers together and divide the sum by the amount of numbers. For example, you would find the mean of 4,5,6,7 â¦ , and 8 by adding them together to get 30.
