You place a piece of potato weighting 0....

You place a piece of potato weighting 0.3 gram with a water potential of 1 MPa in a beaker of Pepsi. After 10 minutes, you remove the potato piece, and it now weighs 0.25 gram. You conclude that

A

Pepsi Cola has a water potential greater than 1 MPa.

B

Pepsi Cola has a water potential of 0 MPa.

C

Pepsi Cola has a water potential less than 1 MPa.

D

Pepsi Cola does not have turgor pressure, and so you cannot conclude anything about its water potential.

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:
