The curve at the surface of a liquid
Pure Substance
a sample of matter, either a single element or a single compound, that has definite chemical and physical properties
Charles Law
the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases
Boyles Law
The relationship between the pressure and volume of a gas at constant temperture; when volume increase, pressure decreases.
Chemical Properties
describes how a substance changes into a new substance, either by combining with other elements or by breaking apart into new substances, includes reactivity and flammability
(chemistry) a substance consisting of two or more substances mixed together (not in fixed proportions and not with chemical bonding)
the dissolved substance in a solution
the degree of hotness or coldness of a body or environment (corresponding to its molecular activity)
the process by which water changes from liquid form to an atmospheric gas, the process of becoming a vapor, the process of extracting moisture
the process whereby heat changes something from a solid to a liquid
Physical Properties
the characteristics of a substance that can be observed or measured without changing the substance
Chemical Change
(chemistry) any process determined by the atomic and molecular composition and structure of the substances involved
the force applied to a unit area of surface
A mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas
Scientific method
a series of steps that scientists use to answer questions and solve problems
Physical Science
the scientific study of nonliving matter
The state of matter in which the volume and shape of a substance are fixed
the process in which a solid changes directly into a gas
in a solution, the substance that dissolves in the solvent
Surface Tension
the force that acts on the surface of a liquid and that tends to minimize the area of the surface
a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
the ratio of the mass of a substance to the volume of the substance
elements that have properties of both metals and nonmetals
the ability of one substance to dissolve in another at a given temperature and pressure
The curve at the surface of a liquid
