Answer 2

Given info : A sample of carbon dioxide has a volume of 20 mL at 330K.

To find : volume of carbon dioxide when the temperature is increased to 100°C.

solution : at the constant pressure, volume of gas is directly proportional to temperature. it is also known as Charles’ law.

i.e., V ∝ T

⇒V₁/V₂ = T₁/T₂

here, V₁ = 20 mL, T₁ = 330K, T₂ = 100°C = 373K

so, 20mL/V₂ = 330/373

⇒20 × 373/330 = V₂

⇒V₂ = 22.6 mL

Therefore the volume of carbon dioxide is 22.6 mL.
