The answer to your question is below
Explanation:
1)
Data
Temperature 1 = 498°C
Pressure 1 = 13.8 atm
Volume 1 = ?
Temperature 2 = 29°C
Pressure 2 = 2 atm
Volume 2 = 18 L
Process
1.- Convert temperature to °K
Temperature 1 = 498 + 273 = 771 °K
Temperature 2 = 29 + 273 = 302 °K
2.- Use the combine law of gas
P1V1/T1 = P2V2/T2
Solve for V1
V1 = T1P2V2 / P1T2
Substitution
V1 = (771)(2)(18) / (13.8)(302)
Simplification
V1 = 27756 / 4167.6
Result
V1 = 6.66 L
2)
Use Boyle's law to solve this problem
P1V1 = P2V2
Data
P1 = 2 atm
V1 = 2.5 L
P2 = ?
V2 = 4 L
- Solve for P2
P2 = P1V1/V2
- Substitution
P2 = (2)(2.5) / 4
- Simplification
P2 = 5 / 4
- Result
P2 = 1.25 atm
