Answer:
359 kPa
Explanation:
Volume remains constant, so we can use GayLussac’s Law.
p₁/T₁ = p₂/T₂ Multiply both sides by T₂
p₂ = p₁ × T₂/T₁
Data:
p₁ = 325 kPa; T₁ = 5.20°C
p₂ = ?; T₂ = 22.5°C
Calculations:
(a) Convert the temperatures to kelvins
T₁ = 5.20 + 273.15
T₁ = 267.95 K
T₂ = 22.5 + 273.15
T₂ = 295.65 K
(b) Calculate the new pressure
p₂ = 325 × 295.65/267.95
p₂ = 325 × 1.105
p₂ = 359 kPa
