What effect do you think a temperature increase has on osmosis?

Answer 1

"Osmosis is not directly affected by temperature, although the general mobility of molecules increases with temperature, and this means a slight increase in osmotic effects with temperature. Since osmosis occurs across membranes, the membrane will be vital to the process, and the protein part of the membrane structure will be denatured at higher temperatures - so no osmosis above about 50°C. Instead the membrane usually becomes fully permeable. "

From BBC's "Ask a Teacher"

Basically, temperature doesn't have a big effect on osmosis until it rises enough to cook the membrane, at which point osmosis ceases and the membrane opens entirely.

Answer 2

Bbc Osmosis

Answer 3

The steady-state will be the same.
The rate will be faster.

The whole process depends upon the integrity of the membrane. If the heat changes the properties of the membrane, these general principles may not be true. For example, if heat makes holes in the membrane, free mixing will occur and there will no longer be osmosis. If the membrane freezes in the solution, transfer may cease.

Answer 4

Temperature increase should speed up osmosis because heat makes the molecules move faster.
