Can a gas be liquefied at any temperature by increase of pressure alone?

No a gas can be liquefied by pressure alone only when temperature of gas is below its critical temperature.

How can gases be liquefied?

In general, gases can be liquefied by one of three methods: (1) by compressing the gas at temperatures less than its critical temperature; (2) by making the gas do some kind of work against an external force, which causes the gas to lose energy and change to the liquid state; and (3) by making gas do work against its …

What happens to the pressure of a gas when you increase the temperature?

The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases.

Why do gases liquify on increasing the pressure and decreasing the temperature explain?

On increasing pressure the volume of the gas decreases which brings gaseous molecules together and decreases the space between them and on decreasing the temperature the kinetic energy of the molecules decreases and forces of attraction between them increases and thus, gas can be converted into liquid.

Can be liquefied by pressure alone when its temperature?

A gas can be liquified by pressure alone only, when its temperature is its critical temperature.

Can a gas be liquefied at any temperature?

A gas can be easily liquefied at any temperature below its critical temperature.

How does applying pressure help in liquefaction of gas?

Answer Expert Verified Pressure brings close to molecules of a gas that are far apart from each other. When more and more pressure is applied on gas molecules they come closer to each other so inter molecular forces start producing between gas molecules. This factor helps in liquefaction of gases.

How can gas be liquefied Brainly?

Answer: Gases can be liquified by applying pressure and lowering the temperature. On applying pressure the gaseous particles come closer and start attracting eachother.

Why does the pressure of a gas increase when the temperature of the gas increases and its volume remains unchanged?

Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.

Why increasing the pressure of the gas would change it from gas to liquid?

So when you put a gas under pressure, the molecules are getting “squished” together and they don’t have a lot of room to move around, so they can’t move away from each other enough and thus liquify.

What is the effect of decreasing temperature and increasing pressure on a gas?

Decreasing temperature decreases the kinetic energy of gas particles and applying pressure decreases the space between particles which in turn strengthens the attractive forces between particles. These changes force the gas to liquefy and change its state to liquid.

Is it possible to liquify a gas by pressure alone?

A gas can be liquified by pressure alone only, when its temperature is its critical temperature.

What happens when you increase the pressure of a gas?

If you increase the pressure of a gas, the temperature will increase. If you reduce the temperature of the gas, the pressure will decrease. The net effect would depend on how much you increase the pressure and how much heat you remove from the gas. Use the Ideal Gas Law that Mark posted, works everytime!

Can a gas exist in a liquid phase?

Below both of these values, a liquid phase can exist. So if we have a gas at one temperature (say ambient) and compress it, then it will get hotter. However, providing it does not exceed the Critical Temperature, it will eventually liquefy when the pressure meets the curve of vapour pressure versus temperature.

What happens when you add more molecules to a gas?

Adding more molecules of a gas increases the number of collisions between the molecules and the walls of the container. This raises pressure. Increase the temperature of the gas. This is represented by “T” in the equation. Increasing temperature adds energy to the gas molecules, increasing their motion and, again, increasing collisions.
