Mercury is often used in clinical thermometers. Which one of the following properties of mercury is not a reason for this?

On the Celsius scale,the temperature of a body increases by $40^{\circ} C$. The increase in temperature on the Fahrenheit scale is: (in $^{\circ} F$)

What is the value of absolute zero temperature on the Fahrenheit scale?

$A$ Celsius and a Fahrenheit thermometer are dipped in boiling water. The temperature of water is lowered until the Fahrenheit thermometer shows $140^{\circ}F$. What is the fall in temperature on the Celsius thermometer (in $^{\circ}C$)?

The correct value of $0^{\circ}C$ on the Kelvin scale is ........ $K$.

If a thermometer reads the freezing point of water as $20^{\circ}C$ and the boiling point as $150^{\circ}C$,what will the thermometer read when the actual temperature is $60^{\circ}C$?
