Question
A thermometer is graduated in mm. It registers - 3mm when the bulb of thermometer is in pure melting ice and 22mm when the thermometer is in steam at a pressure of one atm. The temperature in ∘C when the thermometer registers 13mm is
Answer: Option B
:
B
For a constant volume gas thermometer temperature in ∘centigrade is given as
Tc=P−P0P100−P0×100∘C ⇒ Tc=13−(−3)22−(−3)×100∘C=1625×100
