Explain the process by which plant loses excess of water?

Explanation

Gibb.s free energy (G) is a state function related to enthalpy (H), entropy (S) and temperature (T). IT is expreseed as, G = H - TS
Gibbs fuction, G is an extensive property and a state function. The change is Gibbs energy for the system can be written as follows : `Delta G_("sys") = Delta H_("sys") - T Delta S_("sys") - S_("sys") DeltaT`
At constant temperature `Delta T = 0`
`therefore Delta G_("sys") = Delta H_("sys") - T Delta S_("sys")`
This equation can be simply written as: `Delta G = Delta H - T Delta S`
