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

The temperature of a body on the Kelvin scale is $x \ K$. When the temperature of this body is measured with a Fahrenheit thermometer,it is found to be $x \ ^\circ F$. Then $x = $......

On a temperature scale $X$,the boiling point of water is $65^{\circ} X$ and the freezing point is $-15^{\circ} X$. Assume that the $X$ scale is linear. The equivalent temperature corresponding to $-95^{\circ} X$ on the Fahrenheit scale would be $..........^{\circ} F$.

Find the value of $-197^{\circ} C$ temperature in Kelvin. (in $ K$)

$A$ thermoelectric thermometer is based on:
