$A$ thermocouple is a device for the measurement of

In a mercury thermometer, the ice point (lower fixed point) is marked as $10^{\circ}$ and the steam point (upper fixed point) is marked as $130^{\circ}$. At $40^{\circ} C$ temperature, what will this thermometer read (in $^{\circ}$)?

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

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 the temperature of an object is $140^{\circ}F$,then its temperature in Celsius is ........ $^{\circ}C$.

Write the meaning of temperature.
