Name________________________________________________________________________________ Properties of Matter Study Guide What is Matter? The study of matter and its changes is known as ___________. Matter is anything that possesses both ______ and _________. Matter exists in various states: gas, liquid, solid, and plasma. A ______ has both a defined shape and a defined volume. A ______ has a defined volume, but takes on the shape of its container. A _______ has neither a shape nor a defined volume. A measurement of mass defines the quantity of matter, while ______ is the force of gravity upon this mass. Word Bank: mass, gas, volume, weight, solid, liquid, chemistry ______________ ________________ ____________ The diagrams above represent a microscopic view of matter. Please label them appropriately as solid, gas, or liquid. Chemicals, Mixtures, and Compounds A substance with a defined composition is known as a _____________. A chemical is considered a pure substance. A _____________ mixture is a mixture of substances which is uniform throughout. A liquid homogenous mixture is also known as a ___________. An ____________ mixture is a mixture which is not uniform. A ________ can be separated by physical means, while a ___________ cannot be separated by physical means. Word Bank: homogenous, inhomogenous, chemical, compound, mixture, solution Name________________________________________________________________________________ Please label the following as pure substance, homogenous mixture, or inhomogenous mixture: Sodium bicarbonate (baking soda) Water 5% salt solution Gravel Salty beach sand Cherry Jello Helium gas __________________________________ __________________________________ __________________________________ __________________________________ __________________________________ __________________________________ __________________________________ Properties of Matter A ____________ change is one where a substance changes to a different state but remains the same substance. A ___________ change transforms a substance into one or more new substances. Matter has properties which can be measured: a property which can be measured without a chemical change is known as a ____________ property, while a property which involves a chemical change is known as a ___________ property. Density is a physical property of a substance, which is equal to its ______ divided by its volume.
