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.
Is it true or false critical pressure is the pressure that will cause solid las to liquefy at the critical temperature?
False. Critical pressure is the pressure required to liquefy a substance at its critical temperature, but it does not refer to the pressure that will cause a solid to liquefy. At the critical temperature, a substance cannot exist as a liquid and vapor phase; therefore, the concept of solid melting into a liquid under critical pressure is not applicable.
Why is the melting point of agar useful?
The melting point of agar is useful because it determines the temperature at which agar solidifies and forms a gel. This property makes agar an important ingredient in microbiology labs for culturing bacteria and other microorganisms. By solidifying at a specific temperature, agar provides a solid medium for microbial growth and isolation.
Will all the real gas be liquefied at high pressure?
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
Why is gelatin less suitable than a agar as a solidifying agent for bacteriological media?
Gelatin is less suitable than agar as a solidifying agent for bacteriological media primarily because it is not stable at higher temperatures and can liquefy during incubation. Additionally, gelatin can be digested by some bacteria, leading to inconsistent results and difficulties in isolating colonies. Agar, on the other hand, remains solid at a wide range of temperatures and is not metabolized by most microorganisms, making it a more reliable medium for bacterial growth.
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.
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
Why is the melting point of agar useful?

This property makes agar an important ingredient in microbiology labs for culturing bacteria and other microorganisms. By solidifying at a specific temperature, agar provides a solid medium for microbial growth and isolation.
What temperature makes oxygen liquefy?
Oxygen liquefies at a temperature of -183 degrees Celsius under normal atmospheric pressure.
Why MacConkey agar is solid at room temperature while MacConkey broth remains Liquid at room Temperature?
MacConkey agar contains agar as a solidifying agent which solidifies at room temperature to provide a solid surface for bacterial growth and colony isolation. MacConkey broth, on the other hand, does not contain agar and remains liquid at room temperature to allow for easier culture of bacteria in liquid medium for metabolic studies or growth analyses.
Is ammonia solid at room temperature?
No. Ammonia is a gas at room temperature..
What happens to agar when it cools to room temperature?
It thickens and turns into a gel
What happens to a plate if agar is too hot?
You may kill your bacteria. To avoid this problem we "defrost" the agar in the microwave for 3-8 minutes (depending on how much you have) to liquefy it. It is important to loosen the cap of the agar container so that it doesn't explode in the microwave--never heat a closed system. When the agar comes out of the microwave it is too hot to plate with without the risk of killing your bacteria. Kepp the agar liquid by leaving in a 60 degree C water bath. When the temperature of the agar equilibrates with the bath it should be safe to use.
