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.
A = average (or arithmetic mean) n = the number of terms (e.g., the number of items or numbers being averaged) x1 = the value of each individual item in the list of numbers being averaged. The following is the formula for the arithmetic mean, stated in a more readable and understandable form. A = average (or arithmetic mean) N = the number of terms (e.g., the number of items or numbers being averaged) S = the sum of the numbers in the set of interest (e.g., the sum of the numbers being averaged) One common trap that some students fall into is they automatically divide by 2.
