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 temperature do you keep agar plates at?
25- 30 degree
What is agar jelly and what is it used for?
You can use it to calculate the difference in diffusion rates when dealing with different SA;VOL ratios. The greater the SA;vol ratio, the faster the diffusion. You can do this using Hydrochloric Acid and submerging the cubes in it whilst timing how long it takes for it to permeate the agar jelly cube.
How long does it take non pathogenic Serratia Marcescens D1 to grow and can you use nutrient agar as a medium?
Two days at room temperature on TSA (tryptic soy agar)
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.
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 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.
Why MacConkey agar is solid at room temperature while MacConkey broth remains Liquid at room Temperature?
MacConkey agar is solid at room temperature because it is a gel-like polysaccharide. Broth that has 1.5 percent agar in it and is heated up will become a liquid.
Is it possible to melt a tryptic soy agar slant to make a tryptic soy broth?
No. Agar is a solid at room temperature and would just become solid again. A TSB does not contain agar and therefore can be liquid at room temperature.
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.
What temperature do you keep agar plates at?
25- 30 degree
What happens to agar when it cools to room temperature?
It thickens and turns into a gel
