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 $60^{\circ}C$?

The gas thermometers are more sensitive than liquid thermometers because

$A$ thermometer bulb has a volume of $10^{-6} \,m^3$ and the cross-section of the stem is $0.002 \,cm^2$. The bulb is filled with mercury at $0^{\circ} C$. If the thermometer reads a temperature of $100^{\circ} C$, what is the length of the mercury column? (Coefficient of cubical expansion of mercury $\gamma = 18 \times 10^{-5} /{ }^{\circ} C$)

$A$ centigrade and Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit temperature observed is $140^{\circ} F$. At that time the temperature registered by the centigrade thermometer is (in $^{\circ} C$)

Two thermometers are used to record the temperature of a room. If the bulb of one is wrapped in a wet hanky,which of the following statements is correct?

Which of the curves in the figure represents the relation between Celsius and Fahrenheit temperatures?
