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

The study of physical phenomena at low temperatures (below liquid nitrogen temperature) is called:

Explain the concept of heat and temperature based on everyday experience.

$A$ 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 ...... $^{\circ}$

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
