Question

A student puts five raisins each in two beakers A and B. Beaker A contained 50ml of distilled water at room temperature and beaker B had 50ml of ice cold water. After sometime what will be the observation of the student? State reason for this observation.

Solution

Raisins in beaker A will be more swollen than raisins in beaker B. This is so because osmosis id dependent upon temperature of the solvent particles. Higher the temperature, higher will be energy of the solvent particles, so more endosmosis will take place.

Q. Each of the three beakers A, B and C contained 50 mL of distilled water. A student placed five raisins in each beaker. The raisins for each beaker weighed the same. The beakers were kept at room temperature. The raisins were removed from beaker A after 10 minutes, from beaker B after 20 minutes and from beaker C after one hour. On calculating the percentage of water absorbed by the raisins, it was found that:
(1) maximum absorption of water by raisins was in beaker C
(2) maximum absorption of water by raisins was in beaker B
(3) minimum absorption of water by raisins was in beaker C
(4) absorption of water was equal in raisins of all the three beakers

Q. A student soaked 5 g of raisins in beaker (A) containing 25 mL of ice-chilled water and another 5 g of raisins in beaker (B) containing 25 mL of tap water at room temperature. After one hour the student observed that:
(1) water absorbed by raisins in beaker (A) was more than that absorbed by raisins of beaker (B).
(2) water absorbed by raisins in beaker (B) was more than that absorbed by raisins of beaker (A).
(3) the amount of water absorbed by the raisins of both beakers (A) and (B) was equal.
(4) no water was absorbed by raisins in either of the beakers (A) and (B).
