On the Celsius scale,the temperature of a body increases by $40^{\circ} C$. The increase in temperature on the Fahrenheit 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:

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?

Explain which property of liquid is used with temperature to measure it in a thermometer and how a thermometer represents it.

$A$ faulty thermometer reads $5^{\circ}C$ in melting ice and $95^{\circ}C$ in steam. The correct temperature on the absolute scale will be $.........K$ when the faulty thermometer reads $41^{\circ}C$.

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