Question 170 of 190
Figure shows the variation in temperature with the amount of heat supplied in an isobaric process corresponding to a monoatomic , diatomic and a polyatomic gas. The initial state of all the gases are the same and the scales for the two axes coincide. Ignoring vibrational degrees of freedom, the lines and respectively correspond to :
Show answer and solution
Answer: (B) , and
On giving same amount of heat at constant pressure, there is no change in temperature for mono, dia and polyatomic.
