1.	In the given (V-T) diagram, what is the relation between pressures P_(1) and P_(2) ?
Answer» `P_(2) gt P_(1)` Cannot be PREDICTED `P_(2) = P_(1)` `P_(2) gt P_(1)` SOLUTION :According to ideal gas equation PV = nRT or `V = (nRT)/(P)` For an isobaric process, P = constant and `V prop T` Therefore, V - T graph is a straight line passing through origin. SLOPE of this line is inversely proportional to P. In the given figure, `("Slope")_(2) gt ("Slope")_(1) :. P_(2) lt P_(1)`
