Answer:
V₂ = 395.8 cm³
Explanation:
Given data:
Initial volume = 392 cm³
Initial pressure = 925 torr
Initial temperature = 32 °C (32+273 = 305 K)
Final temperature = -15°C (-15+273 = 258 K)
Final volume = ?
Final pressure = 775 torr
Formula:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 925 torr × 392 cm³ × 258 K / 305 k × 775 torr
V₂ = 93550800 cm³ / 236375
V₂ = 395.8 cm³
