Answer:
0.425 atm
Explanation:
According to Ideal Gas Equation,
- PV = nRT
- Therefore, P ∝ T
- P₁T₂ = P₂T₁
Given :
- P₁ = 0.850 atm
- T₁ = 20.0 C
- T₂ = 30.0 C
Solving :
- 0.85 x 30 = P₂ x 20
- 30 x 17/20 = P₂ x 20
- 510 = 400P₂
- P₂ = 510/400 = 1.275 atm
- Change in pressure = ΔP = P₂ - P₁ = 1.275 - 0.850 = 0.425 atm
