WebAug 19, 2024 · Density is the ratio of the mass of an object to its volume. (1.12.1) density = mass volume (1.12.2) D = m V. Density is usually a measured property of a substance, so its numerical value affects the significant figures in a calculation. Notice that density is defined in terms of two dissimilar units, mass and volume. WebMay 8, 2024 · The Kelvin temperature scale is an absolute temperature scale that is defined using the third law of thermodynamics. Because it is an absolute scale, temperatures recorded in Kelvin do not have degrees. The zero point of the Kelvin scale is absolute zero, which is when particles have minimum kinetic energy and cannot get colder.
