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.
Average and Mean are the same thing. They are the sum of the numbers divided by the number of numbers. The Median is just the number in the middle of the group of numbers. For example, in the number group 1, 2, 6 the number 2 is the median. But the average is (1+2+6)/3 = 3.
