Answer:

V₂ = 19.3 L

Explanation:

Given data:

Initial volume = 29.3 L

Initial pressure = standard = 1 atm

Initial temperature = standard = 273 K

Final temperature = -23°C (-23+273 = 250K)

Final volume = ?

Final pressure = 1.39 atm

Formula:  

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 = 1 atm × 29.3 L × 250 K / 273 K × 1.39 atm

V₂ = 7325 atm .L. K / 379.47  K.atm

V₂ = 19.3 L

kotykmax [81]
Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns. The extent of future climate change depends on what we do now to reduce greenhouse gas emissions. The more we emit, the larger future changes will be
