A gas syringe contains 56.05 mL of a gas at 21.50C. Determine the volume that the gas will occupy if the temperature is increased to 44.30C at the same pressure.

Respuesta :

Answer:

The volume the gas will occupy is 60.39mL

Explanation:

The gas law to be followed here is the Charles' law which states that the volume of a given mass of gas is inversely proportional to its temperature (in Kevin) provided that pressure remains constant. That is V∝T.

Equation thereof = V₁/T₁ = V₂/T₂

where V₁ is the initial volume  (56.05mL)

V₂ is the final volume (unknown)

T₁ is the initial temperature (21.5°C + 273 = 294.5K)

T₂ is the final temperature (44.3°C + 273 = 317.3K)

Thus,

56.05/294.5 = V₂/317.3

V₂ = 56.05 x 317.3/294.5

V₂ = 60.39mL
