 # 3L of nitrogen gas is heated from 20°C to 80°C. What is the new volume of the gas, if pressure remains constant? Answer:              The volume increases to 3.61 L. Solution:                According to Charle's Law, " At constant pressure and mass the volume of gas is directly proportional to the applied temperature". For initial and final states of a gas the equation is,                                            V₁ / T₁  =  V₂ / T₂ Solving for V₂,                                            V₂  =  V₁ T₂ / T₁    ----- (1) Data Given;                    V₁  =  3 L                    T₁  =  20 °C + 273  =  293 K                    T₂  =  80 °C + 273  =  353 K Putting values in eq. 1,                                            V₂  =  (3 L × 353 K) ÷ 293 K                                            V₂  =  3.61 L
