MODULE 3 UNIT 3 Assignment Part D This assignment is to be sent to your instructor for evaluation.1.A sample of argon goes from 500 K to 350 K and its pressure changes from 280 kPa to 380 kPa. If the initial volume is 18 L, what is the final volume? (4 marks)Temperature:Ti= 500KTf= 350KPressure:Pi= 280kPa = 2.76 atmPf= 380kPa = 3.75 atmVolume:Vi= 18LVf= ?Vf= Vi x pi/pf x tf/ti = 18L x 2.76/3.75 x 350/500 = 9.27 L2.A sample of neon experiences a pressure drop from 75 kPa to 53 kPa. The temperature increases from 27oC to 93oC. If the initial volume is 12 L, what is the final volume? (4 marks)Temperature:Ti= 300KTf= 366KPressure:Pi= 75kPa = 0.74atmPf= 53kPa = 0.52atmVolume:Vi= 12Vf= ?Vf= Vi x pi/pf x tf/ti = 18L x 0.74/0.52 x 366K/300 = 31.25 L3.A sample of gas has a volume of 5.23 mL at a pressure of 72.6 kPa and a temperature of 25° C. What will be the volume of the gas if the pressure is
