Why is pressure not proportional to volume if the temperature changes?
Remember that the force of the collisions do not change unless the temperature changes. If the temperature of a gas stays the same, the pressure of the gas increases as the volume of its container decreases.
What happens to volume if temperature increases?
The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value.
What is the effect on the pressure of gas?
Summary. An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.
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.
Which is the most easily liquefiable gas?
Xe
Which noble gas can be liquefied most easily?
Radon
How do you tell which gas will condense first?
If V1V2>1 then gas 1 will condense first, and if V1V2<1 gas 2 will condense first. If V1V2=1 then both will condense simultaneously. If only one of them condenses (V1V2≠1) then we have the simple situation in which the condensate is not a mixture of liquids but is only one kind of liquid.
Which gas will liquefy first oxygen or nitrogen?
(b) Oxygen forms liquid first as the air is cooled. (c) Nitrogen has least boiling point. hence it obtained first.
What’s the difference between oxygen and nitrogen?
All N2 and O2 which are commercially available are produced form of the air. Nitrogen is colourless, odourless and tasteless gas. Oxygen is also without colour, odour and taste. Compared to nitrogen the oxygen reacts with most of the chemical elements.
Can you freeze air?
Yes, you can freeze air, and yes, each ingredient of air will freeze at a different temperature, so that if you were to take a jar of air and slowly make it colder and colder, each different ingredient would freeze into a different layer, just as you suggest.
