Question

Statement (I) : Thermometers using different thermometric property substance may give different readings except at two fixed points. 

Statement (II) : Thermodynamic temperature scale is independent of any particular thermoemtric substance.

(a) Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I) 

(b) Both statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I) 

(c) Statement (I) is true but Statement (II) is false 

(d) Statement (I) is false but Statement (II) is true

Answer 1

(b) Both statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I) 

Thermodynamic or absolute temperature scale is independent of any working substance. The fact that the efficiency of a reversible heat engine cycle depends only on the temperature of the two reservoirs makes it possible to establish such a scale. If the temperature of a given system is mesured with thermometers using different thermoemetric properties, there is considerable difference among the readings.
