Which of the curves in figure represents the relation between Celsius and Fahrenheit temperature 

A hetaed smooth metallic body is allowed to cool in air. Which of the following statements about its heat loss is incorrect?

Find the amount of work done to increase the temperature of 1 mol of an ideal gas by $$30 ^ { \circ } { C }$$ if it is expanding under the condition $$V \propto T ^ { 2 / 3 }$$ .

An ideal gas is expanding such that $$P T ^ { 2 } =$$ constant. The coefficient of volume expansion of the gas is

'n' moles of an ideal gas undergoes a process A $$\rightarrow$$B as shown in figure. The maximum temperature of the gas during the process will be :

A Centigrade and Fahrenheit thermometers are dipped in boiling water. The water temperature is lowered unit the Fahrenheit thermometre registers a temperature of $$140^o$$. The fall of temperature as registered by the Centigrade thermometre is :
