Unit 1: Matter (4A-4D)

An example of a intensive property is

• mass

• density

• volume

• lenth

Solids and Liquids are similar because they

• each have their own volume

• each have their own shape

• can both be deformed easily

• each have quickly moving particles

The following is a physical property

• the flammibility of a piece of paper

• the volume of a rock

• the effect of oxygen on iron

• the ability of silver to tarnish

Compounds are formed when

• elements mix together

• two or more elements are chemically bond

• a solute and a solvent combine

• deposition occurs

Changes of state

• change the identity of a substance

• change the appearance of a substance

• change the mass of a substance

• change the chemical make up of a substance

• sand and beans

• concrete

• a snowglobe

An example of a heterogenous mixture is

• lemonade

• water

• concrete

• calcium
