JEE Main & Advanced Physics Thermometry, Calorimetry & Thermal Expansion Question Bank Self Evaluation Test - Thermal Properties of Matter

  • question_answer
    It \[{{\operatorname{H}}_{K}}, {{H}_{C}}\]and \[{{H}_{F}}\]are heat required to raise the temperature of one gram of water by one degree in Celsius, Kelvin and Fahrenheit temperature scales respectively then

    A) \[{{\operatorname{H}}_{K}}>{{H}_{C}}>{{H}_{F}}\]

    B) \[{{\operatorname{H}}_{F}}>{{H}_{C}}>{{H}_{K}}\]

    C) \[{{\operatorname{H}}_{K}}={{H}_{C}}>{{H}_{F}}\]

    D) \[{{\operatorname{H}}_{K}}={{H}_{C}}>{{H}_{F}}\]

    Correct Answer: C

    Solution :

    [c] \[\frac{C}{5}=\frac{F-{{3}^{2}}}{9}\Rightarrow \frac{\Delta C}{5}=\frac{\Delta F}{9}\] \[\Delta C=\frac{5}{9}\Delta F\Rightarrow \Delta C=\Delta K\]
