Density - The amount of mass per unit volume Density = Mass D = M Volume V

Heat - measure of the quantity or how much energy Temperature - measure of the intensity or how energetic each particle is

Precision and Accuracy Accuracy – How close the measurement is to the true value Precision – how close two or more measurements of the same quantity agree with one another
