Never

Vedclass · Answer

(A) Two isothermal curves represent the relationship between pressure and volume at a constant temperature. If two isothermal curves were to intersect at a single point,it would imply that at that specific point (defined by a unique pressure and volume),the system has two different temperatures simultaneously. Since a system in equilibrium can only have one unique temperature at a given state,it is physically impossible for two distinct isothermal curves to intersect. Therefore,they can never cut each other.
