second option is correct answer
Answer:
Explanation:
Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration. If your tea was too bitter, you could add more sugar to increase the sweetness. Changing the amounts of solute and solvent directly effect the concentration of the solution.
The entropy will increase in pressure if you increase the pressure on the system the volume decrease the energies of the particles are in a smaller space so they are less spread out
Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
