Question

30 cubic meters of argon gas are kept under constant pressure. the gas is heated from 10.0 degrees celsius to 293 degrees celsius. what is the new volume of the gas?

Answer 1

Answer:

            V₂  =  60 cm³

Explanation:

                    According to Charle's Law, "Volume of given amount of gas is directly proportional to applied temperature at constant pressure". Mathematically,

                                                 V₁ / T₁  =  V₂ / T₂    ---- (1)

Data Given:

                   V₁  =  30 cm³

                   T₁  =  10 °C  =  10 + 273  =  283 K

                   V₂  =  ?

                   T₂  =  293 °C  =  293 + 273  =  566 K

Solution:

Solving equation 1 for V₂,

                   V₂  =  V₁ × T₂ ÷ T₁

Putting values,

                   V₂  =  (30 cm³ × 566 K) ÷ 283 K

                   V₂  =  60 cm³
