The ice and steam points of mercury-in-glass thermometer of centigrade scale and of uniform bore correspond respectively to 3cm and 19cm lengths of the mercury thread when the length is 12cm, the temperature is
32oC
48oC
56oC
65oC
75oC

steam point - ice point in oC = 100oC - 0oC
= 19cm - 3cm = 16cm
12cm - 3cm = 9cm
\(\frac{9}{16}\) x 100oC = 56.25oC
= 56oC
= 19cm - 3cm = 16cm
12cm - 3cm = 9cm
\(\frac{9}{16}\) x 100oC = 56.25oC
= 56oC
