Question

A sample of propane gas occupies 691 centimeter cube at 195 K. What is the final volume (in liters) at 272K?}

A sample of Xenon gas at 55.7 psi and 100°C compressed from 3.00L to 0.500 L. If the temperature remains constant, what is the final pressure in atm?}

Answer 1

- ماهر solution, According to Charl's VT when e constant V V T H To 3 geven, st 691 cm 25 T = 155K T2 = 272K V₂ ? 30 now, V₂ Ta = Tax = V 35 691 cm² 272k X 195k im V₂ 963.86

Date Now, cm3 = Inl 963.86 cm3 963.86 m/ V2 =963.86 m/ TL = 1000ml 1000 ml =TL 1 ml 1000 963.86 ml 963.86 L 1000 =0.96386 2 = 0.964 L tinal volume, V₂ =0.964 part-2 According to Boyl's lawi pa t when it conitant) PV = constant PV = P V₂ given P = ? P = 55.7 psi V = 3.002 § = 0'5002 now, PV P P2 V2 PK ½ 55.7 RSI X 3.002 O'500 5 334.2 Psi P2

Date now, 1 aton 14.656 psi = or, 14.696 Psi= I atm Psi atm. 14.696 334.2 Psi X 334.2 atm T4.696 = 22.74 atm. = 22.7 atm [in 3 signiticant itinat pressure P2 = 22.7 atm Ask 10 15
