The temperature on a Fahrenheit temperature scale that is twice the temperature on a Celsius temperature scale is: (in $^{\circ} F$)

On a new temperature scale, the melting point of ice is $20^{\circ} X$ and the boiling point of water is $110^{\circ} X$. $A$ temperature of $40^{\circ} C$ would be indicated on this new temperature scale as (in $^{\circ} X$)

The graph between two temperature scales $P$ and $Q$ is shown in the figure. Between the upper fixed point and the lower fixed point,there are $150$ equal divisions on scale $P$ and $100$ divisions on scale $Q$. The relationship for conversion between the two scales is given by:

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

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

$A$ 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 $\gamma = 18 \times 10^{-5} /{ }^{\circ} C$)
