ANS:C - adsorption

A Thermo Chart, also known as an Enthalpy-Composition diagram, is useful in estimating the heat of mixing in a binary mixture. The heat of mixing refers to the amount of heat released or absorbed when two or more substances are mixed together to form a solution. It is related to the change in enthalpy (Δ𝐻ΔH) of the system. Therefore, the correct option is: mixing
