The temperature of a body shown by a faulty Celsius thermometer is $49^{\circ} C$ and by a correct Fahrenheit thermometer is $122^{\circ} F$. The correction to be applied to the faulty thermometer is

$A$ 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 values of the temperature of a body in Fahrenheit and Celsius scales are in the ratio of $13:5$,then the temperature of the body is

If a graph is plotted with Fahrenheit temperature on the $Y$-axis and Celsius temperature on the $X$-axis,the resulting straight line is one that .....

Maximum density of $H_2O$ is at the temperature

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