Also known as centigrade. • CelsiusA scale and unit of measurement for temperature where 0 °C is the freezing point of water. Also known as centigrade. • chemical bondAny of several attractive forces that serve to bind atoms together to form molecules. • chemical changeA process that causes a substance to change into a new substance with a new chemical formula. • chemical propertyAny characteristic that can be determined only by changing a substance's molecular structure. • chemical reactionA process involving the breaking or making of interatomic bonds and the transformation of a substance (or substances) into another. • chemistryThe branch of science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules. • compoundA substance made from two or more elements. Consists of a fixed ratio of chemically bonded atoms. Has unique properties that are different from the properties of its individual elements. • control groupa group that contains every feature of the experimental group except it is not given the manipulation that is hypothesized • conversion factorA conversion factor changes one unit to a new unit. • densityA measure of the amount of matter contained in a given volume.
