States Of Matter And Changes In Water

The video tutorial explains the changes of state between solid, liquid, and gas, using water as an example. It covers the processes of melting, freezing, condensation, boiling, and evaporation, highlighting their differences and applications. The video concludes with a brief mention of other state changes like sublimation, which are not required for the syllabus.

Which of the following is NOT a state of matter discussed in the video?

• Liquid

• Plasma

• Solid

• Gas

What is the process called when ice turns into water?

• Melting

• Freezing

• Condensation

• Evaporation

What term describes the process of water turning into ice?

• Condensation

• Freezing

• Melting

• Sublimation

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

• Freezing

• Condensation

• Evaporation

• Melting

Which of the following is an example of condensation?

• Ice melting in the sun

• Water vapor forming droplets on a cold glass

• Steam rising from boiling water

• Snow forming from water vapor

What is the difference between boiling and evaporation?

• Neither involves a change of state.

• Boiling occurs at a specific temperature, while evaporation can occur at any temperature.

• Both occur at the same temperature.

• Evaporation occurs at a specific temperature, while boiling can occur at any temperature.
