States of Matter and Phase Changes

The video tutorial explains the three states of matter: solid, liquid, and gas. It details six phase changes: melting, freezing, evaporation, condensation, deposition, and sublimation, providing examples for each process.

What are the three states in which matter can exist?

• Solid, Gas, and Plasma

• Liquid, Gas, and Plasma

• Solid, Liquid, and Gas

• Solid, Liquid, and Plasma

What is the process called when a solid turns into a liquid?

• Condensation

• Freezing

• Melting

• Sublimation

Which of the following is an example of freezing?

• Water turning into steam

• Ice turning into water

• Water turning into ice

• Snow turning into vapor

What happens during evaporation?

• A gas turns into a liquid

• A liquid turns into a gas

• A gas turns into a solid

• A solid turns into a gas

Which process describes a gas changing into a liquid?

• Condensation

• Sublimation

• Melting

• Evaporation

What is deposition in terms of state change?

• A liquid changing into a solid

• A solid changing into a gas

• A gas changing into a solid

• A liquid changing into a gas

Which of the following is an example of sublimation?

• Ice turning directly into water vapor

• Water vapor turning into liquid water

• Steam turning into water

• Water turning into ice

What is the process called when snow changes directly into water vapor?

• Freezing
