Vedclass · Answer

(C) - $(1)$ Ratio of pressure to volume: This is incorrect. The ratio of pressure to volume is not related to enthalpy.- $(2)$ Product of pressure and volume: This is also incorrect. The product of $P$ and $V$ is part of the enthalpy formula but does not define it by itself.- $(3)$ Internal energy $(U)$ + $PV$: This is the correct definition of enthalpy. Enthalpy $(H)$ is defined as the sum of internal energy $(U)$ and the product of pressure $(P)$ and volume $(V)$,i.e.,$H = U + PV$.- $(4)$ Internal energy $(U)$ - $PV$: This is incorrect. Enthalpy involves adding,not subtracting,$PV$ from internal energy.
