How do you liquefy string agar?
To liquefy string agar, you need to heat it gently. Typically, you can place the agar in a water bath or microwave it briefly until it reaches a temperature of about 85-90°C, which allows it to melt. Stirring the agar during heating can help ensure even melting. Once fully liquefied, allow it to cool to the desired pouring temperature before use.
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.
What are the basic steps for pouring agar plates?
To pour agar plates, start by sterilizing your work area and materials, including petri dishes and agar medium. Next, prepare the agar by heating it until fully dissolved, then allow it to cool slightly to avoid condensation. Once at the appropriate temperature (around 45-50°C), pour the agar into the petri dishes, filling them to about one-third to half full. Finally, allow the agar to solidify at room temperature before using the plates for microbial cultures.

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

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..
