Suppose you have a cell from a freshwater fish that is isotonic with its surrounding environment, with a K+ concentration inside the cell of 0.05M. You then immerse this cell in saltwater where the K+ concentration is 0.25M. What would you predict will happen to the cell? a)Water will move into the cell, and the cell will swell and burst b)Water will move out of the cell, and the cell will shrink c)Water will move in and out of the cell with no net change in concentration, and the cell will remain the same size d)The cell wall will prevent the cell from changing size

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
