1a. A sample of neon gas at a pressure of 1.13 atm and a temperature of 20.6 °C, occupies a volume of 597 mL. If the gas is compressed at constant temperature until its pressure is 1.63 atm
The volume of the gas sample will be _______ mL.
1b. A sample of helium gas at a pressure of 1.11 atm and a temperature of 29.1 °C, occupies a volume of 17.4 liters. If the gas is allowed to expand at constant temperature to a volume of 27.5 liters.
The pressure of the gas sample will be______ atm.
1c. A sample of neon gas at a pressure of 0.934 atm and a temperature of 239 °C, occupies a volume of 661 mL. If the gas is cooled at constant pressure until its volume is 572 mL,
the temperature of the gas sample will be _______ °C.
1d. A sample of helium gas at a pressure of 933 mm Hg and a temperature of 72 °C, occupies a volume of 14.1 liters. If the gas is cooled at constant pressure to a temperature of 32 °C,
The volume of the gas sample will be_______ L.
a)
Given:
Vi = 597 mL
Pi = 1.13 atm
Pf = 1.63 atm
use:
Pi*Vi = Pf*Vf
1.13 atm * 597 mL = 1.63 atm * Vf
Vf = 414 mL
Answer: 414 mL
b)
Given:
Pi = 1.11 atm
Vi = 17.4 L
Vf = 27.5 L
use:
Pi*Vi = Pf*Vf
1.11 atm * 17.4 L = Pf * 27.5 L
Pf = 0.702 atm
Answer: 0.702 atm
c)
Given:
Ti = 239.0 oC
= (239.0+273) K
= 512 K
Vi = 661 mL
Vf = 572 mL
use:
Vi/Ti = Vf/Tf
661.0 mL / 512.0 K = 572.0 mL / Tf
Tf = 443 K
Tf = 170 oC
Answer: 170 oC
d)
Given:
Vi = 14.1 L
Ti = 72.0 oC
= (72.0+273) K
= 345 K
Tf = 32.0 oC
= (32.0+273) K
= 305 K
use:
Vi/Ti = Vf/Tf
14.1 L / 345.0 K = Vf / 305.0 K
Vf = 12.5 L
Answer: 12.5 L
