Do gas have melting point

Answer 1

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased. This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.

If V is a constant, the P/T will be a constant - Pressure Law

where V= Volume, P= Pressure and T= Temperature.

If we consider a squash ball to be the sealed container of gas, then the pressure of the gas will vary according to the pressure law. We cannot measure the pressure inside a squash ball, so we make the assumption that the bounce of the ball will be directly proportional to the pressure in the ball. By measuring the "hang-time" (the time between the first and the second bounce) we can make a judgement about what is happening to the pressure inside the squash ball.

Answer 2

Yes, they have. They are gaseous at room temp. but at some temperature they are liquid as well as solid.

For example :- Methane has

Melting point

-182.5 °C, 91 K, -297 °FBoiling point

-161.6 °C, 112 K, -259 °F

Answer 3

Gases do not have a distinct melting point like solids do. Instead, gases turn into liquids through a process called condensation, where the gas molecules lose enough energy to come together to form a liquid. This generally occurs at a specific temperature called the condensation point.

Answer 4

Yes
