3l of nitrogen gas is heated from 20°c to 80°c. what is the new volume of the gas, if pressure remains constant?

             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

True is ur answer : )

Radioactive fallout is a result of the fission creation used to ignite the thermonuclear fusion reaction.
