  • question_answer
    On the Celsius scale the absolute zero of temperature is at

    A) \[0{}^\circ C\]

    B) \[\,32{}^\circ C\]

    C) \[100{}^\circ C\]

    D) \[\text{ }273.15{}^\circ C\]

    Correct Answer: D

    Solution :

    \[T=273.15+t{}^\circ C\] \[\Rightarrow \] \[0=273.15+t{}^\circ C\] \[\Rightarrow \]\[t=-273.15{}^\circ C\]
