One litre glass flask contains some mercury. It is found that at different temperatures the volume of air inside the flask remains the same. What is the volume of mercury in this flask if coefficient of linear expansion of glass is 9×10−6/∘C9 \times {10^{ - 6}}/^\circ C while volume expansion of mercury is 1.8×10−4/∘C.1.8 \times {10^{ - 4}}/^\circ C.
