MODULE 3 UNIT 3 Assignment Part C This assignment is to be sent to your instructor for evaluation. 1.Assuming pressure remains constant, calculate the final volume in each ofthe following cases: (6 points)a)A volume of 35.0 mL of gaseous hydrogen is heated from 20 °C to 120 °C;V1=35.0mL T1=2- Degrees C +273=293K V2= unknown T2=120 degrees C+273=393K V2=35mL*393K/293K=46.945 b)A volume of 15 L of air is chilled from 80 °C to -25 °C.V1=15L T1=80 degrees C +273= 353K V2= unknown T2=-25Degrees C+273=248K V2= 15L*248K/353K=10.538 2.The temperature of a room whose volume is 8.95 x 104L goes from 20 °C to 30 °C. What volume of air will the room lose following this rise in temperature? (3 points) V1=8.95*10^4L T1=20 degrees C +273=293K V2= unknown T2=30 degrees C+273=303K V2=(V1T2)/T1 V2=89500*303/293=92554.607 or 9.25*10^4L 9.25*10^4L -8.95*10^4 =0.3*10^4L The room will lose 0.3*10^4L 3.Calculate the initial volume of a sample of a gas if its final volume is 344 mLafter being heated from -10 °C to 40 °C. (Think carefully here.) (3 points) V1= unknown T1=(-10 Degrees C+273)=263K V2=344mL T2=(40 Degrees C+273)=313K V1=V2T1/T2 V1=344*263/313Answer: V1=289.0479 or 289mL Submission Instructions Submit your assignment using the drop box on the Assignment page for this unit.
