$A$ thermoelectric thermometer is based on:

$Assertion :$ Fahrenheit is the smallest unit measuring temperature.
$Reason :$ Fahrenheit was the first temperature scale used for measuring temperature.

$A$ uniform thermometer scale is at steady state with its $0 \, cm$ mark at $20^{\circ} C$ and $100 \, cm$ mark at $100^{\circ} C$. The temperature of the $60 \, cm$ mark is ............. $^{\circ} C$.

Of the following thermometers, the one which can be used for measuring a rapidly changing temperature is a

In anomalous expansion of water, at what temperature is the density of water maximum?

The saturation vapour pressure of water at $100^{\circ}C$ is ........ $mm$ of mercury.
