Question

What determines the state of a substance? Suggest a method to liquefy gases.water droplets are observed on the outer surface of glass tumbler containing ice cold water. Give reasons

Answer 1

1:The temperature of the substance determines the state of the substance.
2: Gases can be liquified by increasing their pressure or by lowering the temperature of the gas below boiling point ,or by doing both.
3: ...due to condensation of water vapour from the air surrounding the glass tumbler.

Answer 2

The

Intermolecular space

Intermolecular attraction

Kinetic energy determines the state of matter.

Method to liquefy gas is increasing pressure and decreasing tempreture.

The vapours come in contact with air the vapour condenses and become water droplets so droplets are observed on outer surface of the tumbler
