When one mole of an ideal gas is heated from 300 K to 360 K at constan

1.	When one mole of an ideal gas is heated from 300 K to 360 K at constant pressure of 1 atm, its volume ……………. (A) increases from V to 6.0V (B) increases from V to 3.6V (C) increases from V to 1.2V(D) increases from V to 1.6V
Answer» Correct option is: (C) increases from V to 1.2V Using Charles's law V ∝ T, at constant pressure \(\frac {V_1}{T_1} = \frac {V_2}{T_2} \) \(\frac {V_f}{T_f} = \frac {V_i}{T_i} \) \(V_f\) = \(\frac {360\, Vi}{300}\) \(V_f\) = 1.2 Vi Hence, at constant pressure, on heating ideal gas from 300k to 360k, its volume increases from V to 1.2 V (C) increases from V to 1.2V

Answer»

Correct option is: (C) increases from V to 1.2V

Using Charles's law

V ∝ T, at constant pressure

\(\frac {V_1}{T_1} = \frac {V_2}{T_2} \)

\(\frac {V_f}{T_f} = \frac {V_i}{T_i} \)

\(V_f\) = \(\frac {360\, Vi}{300}\)

\(V_f\) = 1.2 Vi

Hence, at constant pressure, on heating ideal gas from 300k to 360k, its volume increases from V to 1.2 V
