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.
Yes, refrigerated agar plates should be brought to room temperature before applying samples. This helps prevent condensation from forming on the surface of the agar, which can interfere with the growth of microorganisms and lead to inaccurate results. Allowing the plates to equilibrate to room temperature also ensures optimal conditions for microbial growth.
Nothing. It is at room temperature.
Whatever the room temperature happens to be at the time. If the room is 75° then the salt would be the same temperature.
Air cooler which cools your limited area, or decreases your room temperature.
Boiling water can increase the temperature of a room by releasing heat energy into the surrounding air. This can lead to a temporary rise in room temperature until the water cools down.
Whatever temperature the room happens to be.
Temperature of a room will goes up.Consider a room as a closed system. The only energy entering or leaving the room is from the AC unit. The AC unit cools some of the air inside the room by pumping refrigerant/coolant and heating up other air of the room (typically that exhaust air would be sent outside). Heat exhausted from the AC pumps increases the temperature of the room.
No, boiling water cools down at a non-constant rate. Initially, it cools down faster as the temperature difference between the water and the room decreases. As the water gets closer to room temperature, the rate of cooling slows down.

Yes, it is possible to melt a tryptic soy agar slant to make a tryptic soy broth. This can be achieved by heating the agar slant in a water bath or microwave until it liquefies, then allowing it to cool and solidify in a tube as a liquid medium. It is important to maintain aseptic techniques during this process to prevent contamination.
Elements in group 18 are gases at room temperature.
