Answer:
The correct option is: d. higher ... lower
Explanation:
Osmosis is a spontaneous process that involves the movement of the solvent particles from the region having <u>low solute concentration to the region having high solute concentration</u>, through a semipermeable membrane. It is a spontaneous process.
Osmosis can also be described as the movement of solvent particles from the region with <u>high solvent concentration to low solvent concentration.</u>
Answer:
Explanation:
Mass and weight are quite different terms .
Weight is defined as the amount of force exerted on the earth due to our mass and gravity of acceleration.
Given that the mass is 90 kg and gravity of acceleration of earth is 9.82 m/s^2.
So weight will be
Answer:
The correct answer is a. The volume of the gas increases.
Explanation:
In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).
If the pressure reduced, the volume increases according to the formula: P1xV1 = P2xV2
The circumstances when scientists use observational research and opinion based research is when they include animals or things that cannot control for a product. Observational research is a type of research which only observes ongoing behavior and studies about it and the results only rely on the behavior observed.
