Define critical moisture content.
It is the moisture content of a material at which the constant rate period ends and the falling rate period starts
It is the moisture contained by a material in excess of the equilibrium moisture content
It is the moisture content of a substance that is in equilibrium with its vapour in the gas phase under the specified humidity and temperature
It is the moisture content in a material which exerts a vapour pressure less than that of the pure liquid at the same temperature.
