Which of the curves in the figure represents the relation between Celsius and Fahrenheit temperatures?

The Fahrenheit and Kelvin scales of temperature will have the same reading at a temperature of (in $^{\circ} F$)

On a temperature scale $X$,the boiling point of water is $65^{\circ} X$ and the freezing point is $-15^{\circ} X$. Assume that the $X$ scale is linear. The equivalent temperature corresponding to $-95^{\circ} X$ on the Fahrenheit scale would be $..........^{\circ} F$.

$A$ faulty thermometer has its fixed points marked $5^{\circ}$ and $95^{\circ}$. This thermometer reads the temperature of a body as $59^{\circ}$. Then,the correct temperature of the body on the Celsius scale is ...... $^{\circ}$

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

$A$ 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:
