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).
Correct answer: (2) water absorbed by raisins in beaker (B) was more than that absorbed by raisins of beaker (A).
Explanation:
It will be observed that the water absorbed by raisins in beaker (B) was more than that absorbed by raisins of beaker (A). It is because rate of imbibition is directly proportional to the temperature. Higher the temperature of water, higher will be the rate of imbibition of water.
