The temperature at which the reading of a Fahrenheit thermometer will be double that of a centigrade thermometer is ........ $^\circ$.

The water on the surface of a lake is just about to freeze. The most likely temperature at the bottom of the lake is (in $^{\circ} C$)

At what temperature in $^\circ F$ is the density of water maximum?

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

The temperature of a body on the Kelvin scale is found to be $X \; K$. When it is measured by a Fahrenheit thermometer,it is found to be $X \; ^\circ F$. Then $X$ is:

$A$ faulty thermometer reads $5^{\circ}C$ in melting ice and $95^{\circ}C$ in steam. The correct temperature on the absolute scale will be $.........K$ when the faulty thermometer reads $41^{\circ}C$.
