Answer:
A glass flask whose volume is 1000 cm ^3 at 0.0 ^oC is completely filled with mercury at this. Every substance when heat energy is supplied, expands due to the Rate of thermal expansion will be different for different materials. Volume of the glass flask and mercury at 0 degree Celsius V0=1000cm3=1×10−3m3 V 0
