Explain why a mercury-in-glass thermometer with a uniform-bore capillary that is correct at 0 celsius and 100 celsius read 49.9 celsius when the temperature is actually 50 celsius. note the volume of a sample of mercury Vt at celsius temperature t, realtive to the volume Vo at 0 celsius, is given by :-
Vt=Vo[1+(0.18182 *10^-3)t+(0.0078*10^-6)t^2]
