Question

match the following terms with the best description.

• concentration of the solution
• osmosis
• osmotic pressure
• semipermeable membrane

solvent in a less concentrated solution passes through a membrane into a more concentrated solution
has an inversely proportional relationship with temperature
has a proportional relationship with temperature
allows only certain particles to pass through
click for list
concentration of the solution
osmosis
osmotic pressure
semipermeable membrane

Explanation:

1. Osmosis is the process where solvent in a less - concentrated solution passes through a membrane into a more concentrated solution.
2. Osmotic pressure has a proportional relationship with temperature (from the van't Hoff equation $\Pi = iCRT$, where $\Pi$ is osmotic pressure, $C$ is concentration, $R$ is the gas constant, $T$ is temperature and $i$ is the van't Hoff factor). It does not have an inversely proportional relationship with temperature.
3. A semi - permeable membrane allows only certain particles to pass through.
4. There is no typical simple inverse or direct proportional relationship between the concentration of a solution and temperature in the context of these terms in a general sense compared to osmotic pressure's relationship with temperature.

Answer:

1. Solvent in a less concentrated solution passes through a membrane into a more concentrated solution: Osmosis
2. Has an inversely proportional relationship with temperature: None of the above (this statement is incorrect for the given terms)
3. Has a proportional relationship with temperature: Osmotic pressure
4. Allows only certain particles to pass through: Semipermeable membrane
