Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.
The economic crisis in most of the European countries was one of the primary reasons for migration in European countries.
Explanation:
Earlier after the end of second world war, many people migrated from country side to developed countries in search for work, with the intend to get a better life. Many unskilled labors got job in developed countries after this world war.
But when countries started facing economic crisis many workers started migrating to their home countries. There was land shortage and job shortage at this time. Farmers faced crop failure
Another cause of this migration was civil war that took place in Spain.
Most people migrated to seek religious, political and personal freedom.
This migration was also impacted by global conflicts also.
