Properties of Matter Review

Milk takes the shape of its container because it is a:

• Solid

• Liquid

• Gas

Answer explanation

Milk takes the shape of its container because it is a liquid. Liquids are able to flow and conform to the shape of their container.

Which state of matter has tightly packed molecules?

• Solid

• Liquid

• Gas

Answer explanation

The state of matter with tightly packed molecules is a solid. In solids, molecules are closely arranged in a fixed structure, which gives them a definite shape and volume, unlike liquids and gases where molecules are more spread out.

What are the 3 states of matter?

• Solid, liquid and air

• Solid, vapor and gas

• Solid, liquid and gas

Answer explanation

The states of matter are solid, liquid, and gas. These states describe the different forms that matter can exist in. The correct choice is solid, liquid, and gas.

What state of matter is this?

• solid

• liquid

• gas

Answer explanation

The correct answer is 'gas' because gases have no fixed shape or volume, allowing them to expand and fill their container moving freely with high kinetic energy.

What is it called when the atoms in the liquid lake begin to move faster and change into a gas?

• melting

• freezing

• evaporation

Answer explanation

When the atoms in a liquid lake move faster, they gain kinetic energy and transition into a gas. This process is known as evaporation, where a liquid turns into vapor due to increased molecular motion.

What happens to the particles in matter when heat is taken away?

• the particles disappear

• the particles gain energy and speed up

• the particles lose energy, slow down and move closer

• there is no change

Answer explanation

When heat is removed from matter, the particles lose energy, causing them to slow down and move closer together. This results in a decrease in temperature and often a change in state, such as from gas to liquid or a liquid into a solid.

What type of change occurs when matter changes states?

• Physical

• Chemical

Answer explanation

When matter changes states, such as from solid to liquid or gas, it undergoes a physical change. This process does not alter the chemical composition of the substance, hence it is classified as a physical change.

When there is one type of atom, we classify this as an....

• Element

• Compound

• Homogeneous Mixture

• Heterogeneous Mixture

Answer explanation

When there is only one type of atom, it is classified as an element. Elements are pure substances that cannot be broken down into simpler substances, distinguishing them from compounds and mixtures.
