In
ecology, pressure-volume curves describe the relationship between total
water potential
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and mat ...

Elastic is a word often used to describe or identify certain types of elastomer, elastic used in garments or stretchable fabrics.
Elastic may also refer to:

plant tissue
In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are ...

According to the Boyle–v'ant Hoff Relation, the product of
osmotic potential and volume of solution should be a constant for any given amount of osmotically active
solutes in an ideal osmotic system.
= A constant
is osmotic potential and
is volume of solution.
This can then be manipulated to a
linear relation which describes the ideal situation:
