Introduction
============
In my investigation to find out how flavor final result minginess affect
the host of murphyes, I will investigate how much the mass of a spud
permutes if I leave it in a beaker of water supply with a specify salt
concentration for half an hour. I will change the salt concentration
after each experiment.
Background friendship
--------------------
Osmosis is the passage of water molecules from a weaker solution to a
stronger solution through a part permeable membrane. A partially
permeable membrane only allows small molecules to pass through, so the
larger molecules remain in the solution they originated in.

The water molecules convey into the more concentrated solution.
When water enters a plant cell it swells up. The water pushes against
the cell paries and the cell eventually contains all that it can hold.
The strong cells wall prevents bursting. The cell is turgid. If plant
cells lose water the cells become hitch and flaccid. Water is essential
for support in plants.
Prediction
I think that when the potato is placed in distilled water the potato
mass will increase.
This is because water, has, if pure, a weaker
concentration than the potato, and the water molecules last in through
a partially permeable membrane by osmosis.
If the potato is in a high concentration salt solution, the potato
mass will decrease because the potato is less concentrated than the
salt solution, and the water will move through the partially permeable
membrane into the stronger solution.
However, if the potato mass stays the same after the experiment, this
means that the water/salt solution and the potato must be of equal
concentration.
