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?

$A$ new temperature scale uses $X$ as a unit of temperature,where the numerical value of the temperature $t_x$ in this scale is related to the absolute temperature $T$ by $t_x = 3T + 100$. If the specific heat of a material using this unit is $1400 \, J \, kg^{-1} X^{-1}$,its specific heat in the $SI$ system of units is:

If the reading in Fahrenheit scale is twice the reading in Celsius scale, then the reading in Fahrenheit scale is (in $^{\circ} F$)

Which of the following figures represents the relation between Celsius $(C)$ and Fahrenheit $(F)$ temperatures?

In the absence of an atmosphere,the average temperature on the surface of the Earth would be . . . . . . .

$A$ certain liquid has a melting point of $-50^{\circ} C$ and a boiling point of $150^{\circ} C$. $A$ thermometer is designed with this liquid and its melting and boiling points are designated at $0^{\circ} L$ and $100^{\circ} L$. The melting and boiling points of water on this scale are
