1
Q
What is osmosis?
A
The passage of water from a region where it has a higher water potential to a region where it has a lower water potential through a selectively permeable membrane.
2
Q
What is a solute?
A
Any substance that is dissolved in a solvent
3
Q
What is water potential measured in?
A
kPa
4
Q
What is the water potential of pure water?
A
zero
5
Q
What happens to the water potential when solute is added to pure water?
A
The water potential lowers
6
Q
What is the water potential of a solution?
A
Less than zero, a negative value
