A flask of mercury is sealed off at

20^{\circ} \mathrm{C}

and is completely filled with mercury. If the bulk modulus for mercury is 2500

\mathrm{MPa}

and the coefficient of volume expansion of mercury is

1.82 \times 10^{-4 /} \mathrm{C}

and the expansion of glass is ignored, the pressure of mercury within the flask at

100^{\circ} \mathrm{C}

will be

View answer and explanation

Correct option: C

36 \mathrm{~MPa}

Option A (

\frac{1}{2}

) is correct because the maximum possible efficiency is calculated using the Carnot efficiency formula.
