A constant volume gas thermometer shows pressure readings of $P_1$ at the triple point of water and $P_2$ at the boiling point of water at 1 atm. What is the ideal gas temperature corresponding to a pressure reading of $2P_1$?

The resistance of the wire in the platinum resistance thermometer at ice point is 5$\Omega$ and at steam point is 5.25$\Omega$.When the thermometer is inserted in an unknown hot bath its resistance is found to be 5.5$\Omega$. The temperature of the hot bath is

Oxygen boils at $\left( { - {{183}^ \circ }C} \right).$ The temperature on the Fahrenheit scale is

Recently, the phenomenon of superconductivity has been observed at $95\,\,K$. This temperature is nearly equal to

A platinum resistance thermometer reads ${0^0}C$ when its resistance is 80 $\Omega$ and ${100^0}C$ when its resistance is 90$\Omega$. Find the temperature at the platinum scale at which the resistance is 86$\Omega$

The freezing point of water on a thermometer is marked as ${20^{\rm{o}}}X$ and the boiling point as ${150^{\rm{o}}}X$ . A temperature of ${80^{\rm{o}}}C$  on this thermometer will be read as

A faulty thermometer reads the melting point of ice as $-10^\circ C$ and the boiling point of water as $110^\circ C$. What will be the correct temperature if this faulty thermometer reads $50^\circ C$?

A pyrometer is calibrated to measure temperatures in the range of 500°C to 2500°C. Which of the following is NOT a valid reason for choosing a pyrometer over a thermocouple in this temperature range?

At what temperature the centigrade and Fahrenheit readings are the same

In a mercury thermometer the ice point (lower fixed point) is marked as ${10^0}$ and the steam point (upper fixed point) is marked as ${130^0}$. At ${40^0}C$ temperature, what will this thermometer read

Mercury boils at ${367^0}C$. However, mercury thermometers are made such that they can measure temperature up to ${500^0}C$. This is done by
