The temperature of liquid nitrogen (LN), an inert cryogenic fluid, is 196 °C (320 °F). To drop the temperature of the concrete as much as is possible without causing it to freeze, LN is directly injected by lances into the batch water storage tank, the aggregate, or the mixer.
<h3>What is Cryopreservation ?</h3>
Cryopreservation is the process of preserving live cells, tissues, and other biological samples by placing them in a deep freezer at extremely low temperatures. The sample is typically stored at 196°C or lower. All of a cell's biological processes come to an end at such low temperatures, and the cell dies.
- Cells and tissues intended for transplantation are frequently stored via cryopreservation. A extremely stable ultra-low temperature environment is provided by liquid nitrogen. It is therefore employed for long-term storage.

NaCl = Sodium chloride
Al(3)O(2) = Aluminium oxide
Answer:
Explanation:
(The MW of CuSO4 is 250 g/mol).
Answer:
27°C or 300K
Explanation
We were told that the pressureof the system decreased by 10 times implies that P2= P1/10
Where P2=final pressure
P1= initial pressure
Wew were also told that the volume of the system increased by 5 times this implies that V2= 5×V1
Where T2= final temperature =-123C= 273+(-123C)=150K
T1= initial temperature
But from gas law
PV=nRT
As n and R are constant
P1V1/T1 = P2V2/T2
T1= P1V1T2/P2V2
T1=2×T2
T1=2×150
T1=300K
=300-273
=27°C
the initial temperature (°C) of a system is 27°C
