For example Oxygen in the air diffused in rivers or ponds for the aquatic animals to breath. The rate of diffusion of liquids is more compared to solids.
This depends only on the initial temperature and the presence of some significant impurities.
Fresh water.
Fresh water
There was salt water but they have replaced it with fresh water.
30% or less of our water is a fresh water
because fresh water supports life on earth.
They spray their fresh produce with water because the produce can dry up. They add water so that the cells have the right amount of water in them, and so that they will stay somewhat fresh. ^Actually, water is not needed in a cell. Water is diffused in a cell so there are equal amount of molecules inside and outside the cell.

Fresh water freezes at a higher temperature than salt water. This is because the presence of impurities in water lowers its freezing point.
The presence of high concentrations of Salt.
The difference is that fresh water will freeze at 0.c and salt will freeze to a lower temperature due to the presence of impurities (salt).
This depends only on the initial temperature and the presence of some significant impurities.
it is caused by a chemical reaction with the metal and the substance. There are many experiments you can do to prove this
diffused reflection
In presence of salt the crystals grow faster because the solubility of salt decreases the solubility of any other compound in water.
Some members of Phylum Porifera show presence of spongin fibers . These fibers are present only in some fresh water sponges which are used as bath sponges .
the Great Lakes are fresh water.( the largest fresh water lakes in the world.)
