Question

A sample of gas occupies 7.80 liters at 425°C? What will be the volume of the gas at 35°C if the pressure does not change?

4.65 liters
3.65 liters
3.44 liters
7.65 liters
5.89 liters

Answer 1

The answer is 3.44 liters

Answer 2

V₁/T₁=V₂/T₂

T₁=425+273.15=698.15 K
T₂=35+273.15=308.15 K

V₂=V₁T₂/T₁

V₂=7.80*308.15/698.15=3.44 L

3.44 liters
