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.

The term 'average' refers to the âmiddleâ or âcentralâ point; when used in mathematics the term average refers to a number that is a typical representation of a group of numbers (or data set). Averages can be calculated in different ways-this page covers the Mean, Median and Mode.uick Giude: To calculate the Mean. Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values). To determine the Median. Arrange the numbers in order, find the middle number. (The middle value when the values are ranked) .
