Properties of Matter Unit Test

Kinley created a model of the molecules of a solid, liquid, and gas to compare the motion of the particles.

Which state of matter does each image represent?

• A - solid, B - liquid, C - gas

• A - gas, B - liquid, C - solid

• A - liquid, B - gas, C - solid

• A - liquid, B - solid, C - gas

Where should plasma be placed in the States of Matter Model?

• Space 1 because as plasma is heated it changes into a solid.

• Space 2 because as a solid is heated it changes into plasma.

• Space 3 because as a liquid is heated it changes into plasma.

• Space 4 because as a gas is heated it changes into plasma.

Penny placed a tablet of baking soda in a cup of water. The tablet immediately began to bubble, fizz, and eventually dissolve.

Did a physical or chemical change occur and how do you know?

• chemical; the tablet gave off a gas in the form of bubbles

• chemical; the fizzing sound indicates a new substance was formed

• physical; the tablet only dissolved in the water and formed a mixture

• physical; the water can be boiled off and the tablet residue would be left

What will happen to molecules in a substance as they are heated?

• They will slow down

• They will speed up

• They will disappear

• They will come together

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles
