CHAPTER 3:PROPERTIES OF MATTER

WHAT IS MATTER?

• Matter is anything that takes up space.
• EX: dog, sand, chair ect.

WHAT IS VOLUME?

• Volume is three-demisonal space.
• While measuring volume of liquid use a graduated cylinder.
• Also use the meniscus. A meniscus is the curve in the liquid.
• Volume is also LXWXH.

WHAT IS MASS?

• Mass- amount of matter in an object.
• Mass and weight are different because mass is measured with a balance.
• Weight is measured is measured with a spring scale.
• Mass measures the amount of matter in an object.
• Weight measure the gravitational force.

PHYSICAL PROPERTY

• Physical property- characteristic of substance that doesn't involve a chemical change
• EX: state, density, ductility ect.
• Density- the amount of matter in a space or volume
• EX: lemons

PHYSICAL CHANGES

• Physical changes- change from one form to another without a change in chemical properties
• EX: a solid popsicle can become a melted popsicle
• You can undo a physical change
• physical changes don't change the idenity property of a substance

CHEMICAL PROPERTY

• Chemical property- matter that shows a substances ability to participate in chemical reaction
• EX: Flammibilty- the ability of a substance to burn

CHEMICAL CHANGE

• Chemical change- change that occurs when multiple subs. Change to new subs.
• EX: ingredients turn into a cake
