Answer :
Nitrogen is a drab fueloline or a liquid below pressure. It is the primary thing of air ,the temperature in degrees when the pressure is changed to 1.65 atm and the volume to 3.24 l is -195.9°C.
WE know.
- PV = nRT
- P = Pressure, V = Volume, n = Number of moles, R = Rygberg constant, T = Temperature
- Case 1
- PV = nRT
- P = 1.37 atm, T = 315 K, V = 15.nine L, R = 0.0821 atm L/mol K
- = 1.37X15.9= nX0.0821X315
- n = 21.783/25.861
- n = 0.8423 moles
- Now we were given the Number of moles of Nitrogen fueloline, we practice ths cost in case 2 to get the Temperature.
- Case 2
- PV = nRT
- P = 1.65 atm, T = ?? , V = 3.24 L, R = 0.0821 atm L/mol K, n = 0.8423 moles
- 1.65X3.24 = 0.8432X0.0821XT
- T = 5.346/0.0692
- T = 77.25 K = (77.25-273.15) °c = -195.9°C.
