What happens to the particles in a solid when heated?

• The particles in a solid lose all energy and become stationary.

• The particles in a solid vibrate more vigorously and may eventually break free from their fixed positions.

• The particles in a solid move freely and do not interact with each other.

• The particles in a solid expand and become liquid immediately.

Which property describes how easily a liquid flows?

What is the shape of a gas in a container?

• The shape of a gas is always a perfect sphere.

• Gases do not take the shape of their container.

• The shape of a gas is fixed and does not change.

• The shape of a gas in a container is the same as the shape of the container.

Which state of matter has a fixed volume but not a fixed shape?

• Solid
