A student soaked 5 g of raisins in beaker (A) containing 25mL 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:

Each of the three beakers A, B, and C contained 50 mL of distilled water. A student placed five reisins 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:

A student dissolved 5 g of sugar in 100 mL of distilled water in beaker A. He dissolved 100 g of sugar in 100 mL of distilled water in beaker B. Then he dropped a few raisins of equal weight in each beaker. After two hours he found the raisins in A swollen and those in B shrunken. The inference drawn is that:

A student put five raisins each in two beakers A and B. eaker A contained 50 mL of distilled water and beaker B had 50 mL of saturated sugar solution. After some time the student would observe that

The following data was obtained on performing an experiment for determining the percentage of water absorbed by raisins: {:("Mass of water in the beaker",=50g),("Mass of dry raisins",=20g),("Mass of raisins after soaking in water",=30g),("Mass of water left in the beaker after the experiment",=40g):} The percentage of water absorbed by raisins will be :

A solid substance having a temperature of 90^@C is kept in a beaker. Some water having temperature of 60^@C is then poured into the beaker. After sometime, the temperature of the water will be

5 dry raisins were placed in each of the two beakers containing 50 mL of water. After four hours, the raisins were taken out and wiped. For calculating the percentage of water absorbed by raisins, the raisins should have been weighed:

Two beakers A and B are filled to the brim with water at 4 °C. When A is heated and B is cooled, the water

Archit dropped a crystal of potassium permanganate into two beakers A and B containing hot water and cold water respectively. After keeping the beakers undisturbed for some time what did he observe and why ?
