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

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

The resistance of the platinum wire of a platinum resistance thermometer at the ice point is $5\; \Omega$ and at steam point is $5.39\; \Omega$. When the thermometer is inserted in a hot bath,the resistance of the platinum wire is $5.795\; \Omega$. Calculate the temperature of the bath in $^oC$. (in $^{\circ}C$)

In a mercury thermometer, the ice point (lower fixed point) is marked as $10^{\circ}$ and the steam point (upper fixed point) is marked as $130^{\circ}$. At $40^{\circ} C$ temperature, what will this thermometer read (in $^{\circ}$)?

$A$ Centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit thermometer registers $140\,^{\circ}F$. What is the fall in temperature as registered by the centigrade thermometer?

At what temperature is the density of water maximum? Provide the value in $^\circ C$, $^\circ F$, and $K$.
