Two thermometers are constructed in the same way except that one has a spherical bulb and the other a cylindrical bulb; which one will respond quickly to temperature changes?

At the top of a mountain, a thermometer read ${7}^{0}C$ and barometer reads $70\, cm$ of Hg. At the bottom of the mountain, the barometer reads $76\,cm$ of Hg and thermometer reads ${27}^{0}C$. The density the density at the bottom.

A thermometer reads $0^{\circ}$ as $10^{\circ}$ and $100^{\circ}$ as $90^{\circ}C$. Then
Find the reading of the temperature if the temperature is $40^{\circ}C$?

If two temperatures differ by 25 degrees on Celsius scale, the difference of temperature on Fahrenheit scale is 

A Centigrade and Fahrenheit thermometers are dipped in boiling water. The water temperature is lowered unit the Fahrenheit thermometre registers a temperature of $140^o$. The fall of temperature as registered by the Centigrade thermometre is :

On a new scale of temperature (which is linear) and called the W scale, the freezing and boiling points of water are $39^o$W and $239^o$W respectively. What will be the temperature on the new scale, corresponding to a temperature of $39^o$C on the Celsius scale ?

The range of a clinical thermometer is

People boil water as safe measure to drink because:

At low temperatures ________  type of thermometer is used.

The most commonly used thermometric substance is
