Answer:
1,15mL = V₂
Step-by-step explanation:
Based on Charle's law the volume is directely proportional to the absolute temperature in a gas under constant pressure. The equation is:
V₁T₂ = V₂T₁
Where V is volume and T absolute temperature of a gas where 1 is initial state and 2, final state.
The V₁ is 1.23mL
T₁ = 32°C + 273.15 = 305.15K
T₂ = T₁ - 20°C = 285.15K
Replacing:
1.23mL*285.15K = V₂*305.15K
1,15mL = V₂
