What is absolute zero temperature?

The temperature on a Fahrenheit temperature scale that is twice the temperature on a Celsius temperature scale is: (in $^{\circ} F$)

If $H_C, H_K$ and $H_F$ are the heat required to raise the temperature of one gram of water by one degree Celsius,Kelvin,and Fahrenheit temperature scales respectively,then:

$Assertion :$ Fahrenheit is the smallest unit measuring temperature.
$Reason :$ Fahrenheit was the first temperature scale used for measuring temperature.

Write the equation that gives the relation between $t_F$ and $t_C$.

On a new scale of temperature (which is linear) called the $W$ scale,the freezing and boiling points of water are $39\,^{\circ}W$ and $239\,^{\circ}W$ respectively. What will be the temperature on the new scale,corresponding to a temperature of $39\,^{\circ}C$ on the Celsius scale?
