Asample of gas in a balloon has an initial temperature of 20. ∘c and a volume of 1.92×103 l . if the temperature changes to 68 ∘c , and there is no change of pressure or amount of gas, what is the new volume, v2, of the gas?

Explanation:

The pressure is constant, so we can use Charles' Law.

Data:

V₁ = 1.92 × 10³ L; T₁ = 20 °C  

V₂ = ?;                 T₂ = 68 °C

Calculations:

(a) Convert temperatures to kelvins

T₁ = (20 + 273.15) K = 293.15 K

T₂ = (68 + 273.15) K = 341.15 K

(b) Calculate the volume

The new volume of the gas is .
