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.
An average is a value that acts as a good representative of a set of numbers. Mathematically, the average is the sum of all values, divided by the number of values â¦ there are. This is known as the arithmetic mean. There are also two other forms of average, other than the arithmetic mean.
