Standardisation of thermometers is obtained with

$A$ faulty thermometer has its lower fixed point marked as $-10^\circ C$ and upper fixed point marked as $110^\circ C$. If the temperature of a body shown on this scale is $62^\circ$,the temperature shown on the Celsius scale is ........ $^\circ C$.

Two absolute scales $A$ and $B$ have triple points of water defined to be $200\; A$ and $350\; B$. What is the relation between $T_{A}$ and $T_{B}$?

$A$ constant volume gas thermometer shows pressure readings of $50 \, cm$ and $90 \, cm$ of mercury at $0^{\circ} C$ and $100^{\circ} C$ respectively. When the pressure reading is $60 \, cm$ of mercury,the temperature is ......... $^{\circ} C$.

Mercury thermometers can be used to measure temperatures up to ........ $^oC$. (in $^oC$)

What is the difference between $^oC$ and $^oF$ thermometer values for freezing and boiling points of water?
