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.
Definition. Simple or arithmetic average of a range of values or quantities, computed by dividing the total of all values by the number of values. For example, the mean of 1, 2, 3, 4, and 5 is (15 Ã· 5) = 3.efinition.
