Is it possible to liquefy c02 at a temperature of 40 degrees celsius?

The critical temperature for carbon dioxide is 304K (87.8°F [31°C]). That means that no amount of pressure applied to a sample of carbon dioxide gas at or above 304K (87.8°F [31°C]) will cause the gas to liquefy. At or below that temperature, however, the gas can be liquefied provided sufficient pressure is applied. The corresponding critical pressure for carbon dioxide at 304K (87.8°F [31°C]) is 72.9 atmospheres (~73000 kPa). In other words, the application of a pressure of 72.9 atmospheres of pressure on a sample of carbon dioxide gas at 304K (87.8°F [31°C]) will cause the gas to liquefy.

What temperature does agar liquefy?
Depending on the media agar solidifies at 32 to 40 degrees Celsius. It remains firm up to about 65 degree Celsius.
How can you liquefy a gas?
All forms of gas will liquefy at a sufficiently low temperature.
Can you liquefy a gas?
All forms of gas will liquefy at a sufficiently low temperature.
What happens to oxygen at 183 degree Celsius?
That is the boiling point of oxygen. So if the temperature in going downwards then oxygen will begin to liquefy whereas if the temperature is rising, then liquid oxygen will begin to boil.
How do you use the word Liquefy in a sentence?
You can liquefy metal by heating it to a high enough temperature.
Is it true that above the temperature no amount of pressure will casue a gas to liquefy?
The critical temperature of a gas is the temperature at or above which no amount of pressure, however great, will cause the gas to liquefy.
What is the temperature required to liquefy a gas?
Depends which gas
What is the importance of pressure?
It liquefy the gas at its critical temperature
What is the importance of critical pressure?
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
Can a gas freeze?
A solid is already 'frozen'. Many solids will liquefy when heated, so their solid forms are the result of cooling down again, though the solid/liquid change may occur at hundreds of degrees celsius. Gases will liquefy before freezing, but will freeze if cold enough. Thus nitrogen liquefies at -196 celsius and freezes at -210 celsius, hydrogen liquefies at -252 celsius and freezes at -259 celsius, and helium liquefies at -269 celsiusand freezes at -272 celsius, which is about 1 degree above absolute zero.
Is chlorine solid liquid or gas?
--------------------------------------------------------------------------- At normal conditions of temperature and pressure chlorine is a gas. --------------------------------------------------------------------------- Chlorine is not a solid, those tablets you get for your pool are not elemental chlorine. They are often hypochlorites (bleaches), but can be many different chemicals that allow introduction of chlorine into the pool water. You can liquefy chlorine at about -30C (not much colder than your freezer), and freeze it at about -100C. But if you happened to have found a bucket full of chlorine sitting around, it'd be a gas.
What temperature does gas freeze at?
That is impossible to answer. It depends on which gas you are talking about and its pressure. At standard atmospheric pressure, oxygen freezes at -218.8 degrees C. Of course, under most circumstances the gas will liquefy before it freezes.
