Matter and Its Properties Chapter E 1

Matter and Physical Properties (E 6) All things are made up of _____, which

Matter and Physical Properties (E 6) All things are made up of _____, which is anything that has mass and takes up space Each object has its own set of characteristics, or _____ and examples include color, hardness, and an ability to conduct electricity ______ properties are characteristics of a substance that can be observed or measured without changing the substance into something else

Mass and Weight (E 7) One physical property which is the amount of matter

Mass and Weight (E 7) One physical property which is the amount of matter in an object we call ______ Weight is also a physical property and it depends on the amount of matter and the force of _____ So, ______ is a measure of the pull of gravity on an object _____ can therefore change when outside the force of gravity, but _____ always remains the same Weight is measured on a spring ____ so that the pull of gravity and the mass of the object can be measured Mass is measured using a ______ where the mass of the object can be compared and also to avoid measuring the pull of gravity

Volume (E 8) Matter not only has mass but also takes up space, and

Volume (E 8) Matter not only has mass but also takes up space, and _____ is the amount of space that an object takes up The volume of a _____ can be measured using a graduated cylinder, a clear tube marked in milliliters The volume of some _____ can be calculated using a formula of ________ x _______ For objects with an irregular shape, volume can be measured by placing the object in measured amount of liquid and seeing how much is _______. The volume is the difference between the volume of the water and the volume of the object and water

Density (E 9) ____ and _____ on their own are not able to identify

Density (E 9) ____ and _____ on their own are not able to identify an unknown object or substance If you have measurements of the mass and volume, you can calculate the _____ of the object Density is the _______ of matter in an object Density is calculated by ______ volume by the mass Pure substances have the ____ density and this allows density to be used in identifying a substance Must have the substance’s _____ and _____ to calculate the density

Mixtures & Solutions (E 10 -11) While some substances are pure, most are _____,

Mixtures & Solutions (E 10 -11) While some substances are pure, most are _____, which is a combination of two or more different kinds of matter, each of which keeps its own physical ______ There a variety of ways to _____ a mixture into the substances that make them up When one substance dissolves in another, the two form a _______ and they cannot be easily separated The solubility of substances, or their ability to be ______, can be used to help identify what the substance is Solutions can combine a liquid and a solid, two or more ___________, or two or more ______

Three States of Matter (E 14) The state in which matter is at any

Three States of Matter (E 14) The state in which matter is at any point depends on conditions such as ______ and pressure A solid has definite _____ and a definite _____ A ______ has a definite volume but no definite shape A gas does not have a definite ____ or _____

Particles of Matter (E 15) All matter involves particles in _____ In a _____,

Particles of Matter (E 15) All matter involves particles in _____ In a _____, the particles are very close together and this squeezing of particles gives them a definite volume and _____. Particles stay in the same place and ______ only Particles in a _____ move more freely than in a solid, so they often take the shape of its container _____ particles have the most freedom of movement and its particles move the fastest. An increase in_____ can push fast-moving particles together If the pressure applied is high enough and the temperature lowers, a gas may become a ______

Changes Between States (E 16 -17) All substances are able to change ____, namely

Changes Between States (E 16 -17) All substances are able to change ____, namely through changes in _____ and pressure ______ is a change in state from solid to liquid and _____ changes a substance from liquid to gas Evaporation occurs when particles escape from a nonboiling liquid and become a _____________ changes a substance from a gas to a liquid Changes in state do not change the _______, and changes in state are ______ Changes in state occur when _____ is removed or added When heat is added, the particles in the substance gain ______, and they move _____ and _____ apart When heat is _______ the particles slow down and move ________ together

Melting and Boiling Points (E 18) The term freezing refers to the ______ at

Melting and Boiling Points (E 18) The term freezing refers to the ______ at which water boils Every substance however has its own freezing point, or temperature at which it changes from a _____ to a ______ Substances that are solids at room temperature have very _____ freezing points The temperature at which a substance changes from a liquid to a gas is called it _____ point The difference between the boiling point for water and carbon is ______ degrees Most substances can be identified by their ______ and ______ points since different substances melt and boil at different temperatures

Physical and Chemical Changes (E 22 -23) Changes that involve a change in state

Physical and Chemical Changes (E 22 -23) Changes that involve a change in state but not the creation of new substances are called _____ changes Changes in which one or more new substances are formed are called ____ changes Chemical reactions involve _____, or the starting substances and _____ or the new substance One example of a chemical change is _____ something ______ is a substance’s ability to react chemically to changes Chemical reactions may be identified when there is a change in _____ or the creation of _____, or gas
