Increasing the temperature of a group of molecules affects their movement by causing it to

• Increase

• Decrease

• Slow

• Not cause change

A glass of water is a pure substance because it

• Only made of one compound

• Only made of one element

• Made of several compounds

• Is a balanced mixture

If you mix multiple elements together without binding them they are considered

• A compound

• A mixture

• An element

• A chemical change

A compound can be described as

• A single isolated element

• Different elements floating freely

• Different elements bound together

• A mixture of elements

By combining a liquid and gas under pressure (like shaving cream) you have a

• Solution

• Homogeneous Mixture

• Suspension

• Colloid

Ice tea has evenly distributed particles in water, making it a

• Heterogeneous Mixture

• Homogeneous Mixture

• Suspension

• Colloid

A difference between suspensions and solutions is

• Suspensions have unmixed particles, solutions don’t

• Suspensions have completely mixed particles, solutions don’t

• Solutions are characterized by solids only

• Solutions can be separated easier than suspensions

By increasing pressure, state of matter may change because ​ ​ (a)   will increase

• Weight

• Mass

• amount of particles
• Temperature
