    If the pressure of a gas contained in a vessel is increased by 0.4% when heated through \[1{}^\circ C\], the initial temperature had been :

    A)  2500 K                                 

    B)  250 K

    C)  \[250{}^\circ C\]                                             

    D)  \[25{}^\circ C\]

    Correct Answer: C

    Solution :

                    According to Charles law \[\frac{dP}{P}=\frac{dT}{T}\] Here:      \[dT={{1}^{o}}C\] dP is change in pressure = 0.4%                 \[\frac{dP}{P}=\frac{0.4}{100}\] or            \[\frac{0.4}{100}=\frac{1}{T}\] So,          \[T=\frac{100}{0.4}={{250}^{o}}C\]
