An ideal thermometer should have

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

$A$ Celsius and a Fahrenheit thermometer are dipped in boiling water. The temperature of water is lowered until the Fahrenheit thermometer shows $140^{\circ}F$. What is the fall in temperature on the Celsius thermometer (in $^{\circ}C$)?

If a graph is plotted taking the temperature in Fahrenheit along the $Y-$axis and the corresponding temperature in Celsius along the $X-$axis,it will be a straight line:

The temperature of the hot junction of a thermocouple is increased from $80\,\,^{\circ}\text{C}$ to $100\,\,^{\circ}\text{C}$. The percentage change in the thermoelectric power will be ............ $\%$.

Oxygen boils at $-183^{\circ} C$. This temperature is approximately (in $^{\circ} F$)
