Question

164.Which is always negative (under natural condition)? 1. S 2. W of solution 3. P 4. P of solution 1. 1, 2 only 2. 1 only 3. 4 only 4. 3 only

Answer 1

Answer:

1.S.2. W

Explanation:

1.S.2. W

it is your answer.

Answer 2

OPTION (1) IS CORRECT.

1. 1, 2 ONLY

Explanation:

• The equation of the water potential is given by ψ(W)=ψ(S)+ψ(P).
• The solute potential is always negative as the amount of solute increases, the concentration increases and as a result it decreases and becomes negative.
• The water potential is also negative as for pure water the standard potential is taken 0 and when solute it added it decreases.
• Pressure potential can be positive or negative.
• Therefore, option 1. is correct as ψ(W) and ψ(S) are both negative.
