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

On the Celsius scale,the absolute zero of temperature is at .......... $^\circ C$.

The triple point of water is

The temperature of a body on the Kelvin scale is found to be $X \; K$. When it is measured by a Fahrenheit thermometer,it is found to be $X \; ^\circ F$. Then $X$ is:

The melting point of ice and the boiling point of water are marked as $20^o X$ and $150^o X$ respectively on a thermometer. What will be the temperature of $60^o C$ on this scale?

The absolute zero temperature on the Fahrenheit scale is ........ $^\circ F$.
