The volume of an ideally behaving gas is 300 L at 227°C. What volume will the gas occupy at 27°C when pressure remains constant?

Explanation:

Initial volume, V₁ = 300 L

Temperature, T₁ = 227°C

New temperature, T₂ =  27°C

We need to find the volume of gas occupied when the temperature is 27°C.

It is based on Charle's law. A/c to Charle's law,

(at constant pressure)

Hence, the new volume is 35.68 L.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
