Question

Defination of diffusion pressure

Answer 1

"The potential ability of a substance to move from a region of high concentration to a region of low concentration at a constant, temperature end atmospheric pressure is called diffusion pressure."

Answer 2

The term diffusion pressure deficit (DPD) was coined by B.S Meyer in 1938. ... It is a reduction in the diffusion pressure of water in solution or cell over its pure state due to the presence of solutes in it and forces opposing diffusion.
