Question

A 150 mL sample of gas is collected at 36 deg. C. What volume would the gas occupy at 49 deg. C? Be sure to answer in the correct number of significant figures and correct unit

Answer 1

Charles' Law states that volume and temperature (in Kelvin) are directly proportional for a gas, mathematically written as V₁/T₁ = V₂/T₂

Scenario 1: 150 mL at 36ºC

1. V₁ = 150 mL
2. T₁ = 36 + 273 = 309 K

Scenario 2: __ mL at 49ºC

1. V₁ = __ mL
2. T₁ = 49 + 273 = 322 K

V₁/T₁ = V₂/T₂

150 mL / 309 K = V₂ / 322 K

V₂ = 160 mL
