What state of matter does this picture show?

• Liquid

• Gas

• Solid

• Plasma

Answer explanation

The picture shows a gas state of matter. Gas is a state of matter that has no definite shape or volume and fills the entire space available to it.

The molecules in the picture are tightly held together with little movement. They have shape and energy. Therefore, the picture represents _________.

• solid

• liquid

• gas

• plasma

Answer explanation

The molecules in the picture are tightly held together with little movement, indicating a solid state. This choice is correct because solids have shape and energy.

The state of matter that is made of ionized matter and is most rare on Earth

• solid

• liquid

• gas

• plasma

Answer explanation

Plasma is the state of matter made of ionized matter and is rare on Earth. It is different from solid, liquid, and gas.

A state of matter that takes the shape of its container. Its particles are spaced widely. You can't usually see it.

• Solid

• Liquid

• Gas

• plasma

Answer explanation

Gas is a state of matter that takes the shape of its container, with widely spaced particles. It is usually invisible.

State of matter that has volume and takes the shape of its container. Therefore, it is a ______________.

• solid

• liquid

• gas

• plasma

Answer explanation

A state of matter that has volume and takes the shape of its container is called a liquid. It is the correct choice because liquids have these properties.

A plasma can be made in a laboratory by

• cooling a gas to very low temperatures

• cooling a gas and reducing the pressure

• heating a gas to extremely hot temperatures

• heating a liquid to the point it turns into a gas

Answer explanation

A plasma can be created in a laboratory by heating a gas to extremely hot temperatures. This process ionizes the gas, creating a state of matter with charged particles. Cooling a gas to very low temperatures, cooling a gas and reducing the pressure, and heating a liquid to the point it turns into a gas do not result in the formation of plasma.

Particles in this state of matter are moving the slowest.

• solid

• gas

• liquid

• plasma

Answer explanation

Particles in the solid state of matter move the slowest. This is because the particles in a solid are tightly packed and have the least amount of energy compared to particles in other states of matter.
