1. Take three raisins and weigh them on the common balance. Let this value be W1.
2. Keep these raisins in a bowl containing water for 2 hours.
3. Take the raisins out of the water and gently dry them with the help of blotting paper.
4. Weigh the soaked swollen raisins again on the common balance. Let this value be W2.
The soaked swollen raisins (W2) weigh more than the dry raisins (W1). This is because the raisins absorbed water by the process of endosmosis.
