States of Matter and Changes of State

What happens during freezing?

• Freezing is the process where a liquid changes into a solid when cooled.

• Freezing is the process where a solid changes into a liquid when heated.

• Freezing is the process where a gas turns into a liquid when cooled.

• Freezing is the process where a liquid evaporates into a gas when heated.

What is viscosity?

• A measure of a fluid's resistance to flow.

• The temperature at which a fluid boils.

• The density of a fluid at a given temperature.

• The speed at which a fluid flows through a pipe.

What is sublimation?

• The process where a solid changes directly into a gas without becoming a liquid first.

• The process where a gas changes into a liquid.

• The process where a liquid changes into a solid.

• The process where a solid changes into a liquid.

In which state of matter are particles tightly packed in fixed positions?

• In a solid state of matter, particles are tightly packed in fixed positions.

• In a liquid state of matter, particles are loosely packed and can flow.

• In a gaseous state of matter, particles are far apart and move freely.

• In a plasma state of matter, particles are ionized and free-moving.

What is condensation?

• The process where water vapor in the air cools and changes into liquid water, forming droplets.

• The process of water evaporating into vapor due to heat.

• The process of ice melting into water when heated.

• The process of water being absorbed by soil and plants.

What is a liquid?

• A state of matter that has a definite volume but takes the shape of its container.

• A state of matter that has a definite shape and volume.

• A state of matter that can be compressed easily.

• A state of matter that has no definite volume or shape.

What is a gas?

• A gas is a state of matter with a definite shape and definite volume.

• A gas is a state of matter with an indefinite shape and indefinite volume.

• A gas is a liquid that has evaporated.

• A gas is a solid that has melted.

What is the kinetic molecular theory?

• It states that matter is composed of particles that are in constant motion, and this motion is related to temperature.

• It describes how matter can exist in different states without changing its composition.

• It explains the behavior of gases under high pressure and low temperature conditions.

• It suggests that all matter is made up of solid particles that do not move.

What happens during melting?

• Melting is the process where a solid changes into a liquid when heated.

• Melting is the process where a liquid changes into a gas when heated.

• Melting is the process where a solid becomes a gas without becoming a liquid.

• Melting is the process where a liquid changes into a solid when cooled.

What is a solid?

• A state of matter with a definite shape and definite volume.

• A state of matter that flows and takes the shape of its container.

• A state of matter that has no definite shape but a definite volume.

• A state of matter that can be compressed easily.
