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 of a set of numbers, sometimes simply called the average, is the sum of the data divided by the total number of data. Example 1 : Find the mean of the set {2, 5, 5, 6, 8, 8, 9, 11}. There are 8 numbers in the set. Add them all, and then divide by 8.
