Question
Which of the following volume $$(V)$$ - temperature $$(T)$$ plots represents the behaviour of one mole of an ideal gas at one atmospheric pressure ?
A.
B.
C.
D.
Answer :
Solution :
$$\eqalign{ & \frac{{{V_1}}}{{{T_1}}} = \frac{{{V_2}}}{{{T_2}}}\,\,{\text{at const}}{\text{. pressure}} \cr & \Rightarrow \frac{{22.4}}{{273}} = \frac{{{V_2}}}{{373}},\,{V_2} = 30.6\,{\text{litre}} \cr} $$
$$\eqalign{ & \frac{{{V_1}}}{{{T_1}}} = \frac{{{V_2}}}{{{T_2}}}\,\,{\text{at const}}{\text{. pressure}} \cr & \Rightarrow \frac{{22.4}}{{273}} = \frac{{{V_2}}}{{373}},\,{V_2} = 30.6\,{\text{litre}} \cr} $$
