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

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

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

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 $^{\circ} X$)

Two thermometers $X$ and $Y$ have ice points marked at $15^{\circ}$ and $25^{\circ}$ and steam points marked as $75^{\circ}$ and $125^{\circ}$ respectively. When thermometer $X$ measures the temperature of a bath as $60^{\circ}$ on it,what would thermometer $Y$ read when it is used to measure the temperature of the same bath? ...... $^{\circ}$

If the temperature of an object is $140^{\circ}F$,then its temperature in Celsius is ........ $^{\circ}C$.
