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= 500K Tf= 350K Pressure: Pi= 280kPa = 2.76 atm Pf= 380kPa = 3.75 atm Volume: Vi= 18L Vf= ? Vf= Vi x pi/pf x tf/ti = 18L x 2.76/3.75 x 350/500 = 9.27 L 2. A sample of neon experiences a pressure drop from 75 kPa to 53 kPa. The temperature increases from 27 o C to 93 o C. If the initial volume is 12 L, what is the final volume? (4 marks) Temperature: Ti= 300K Tf= 366K Pressure: Pi= 75kPa = 0.74atm Pf= 53kPa = 0.52atm Volume: Vi= 12 Vf= ? Vf= Vi x pi/pf x tf/ti = 18L x 0.74/0.52 x 366K/300 = 31.25 L 3. 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
