Question

which statement is wrong regarding osmotic pressure volume and temperature
1) pv is constant if T is constant
2)pressure is directly proportional to volume
3)preasure is directly proportional to temperature
4)preasure is inversaly proporational to volume​

Answer 1

Explanation:

The answer is 2,4, ..

I HOPE IT WILL BE RIGHT ANSWER.....

Answer 2

Answer:

The above formula infers that osmotic pressure is directly proportional to factors such as concentration, gas constant and temperature. Thus it is inferred that as osmotic pressure is directly proportional to temperature increases with increase in temperature and decreases with decrease in temperature

Explanation:

Osmotic pressure is defined as "the excess pressure that needs to be applied to a solution to prevent osmosis when a solution is separated from the solvent by a semi permeable membrane. It is usually denoted by '."

P=

v

n

RT.

v

n

=C.

P=CRT.

where,

C = Concentration of the solution in moles per liter.

R = Gas constant.

T = Temperature.

n = Number of moles of the solute.

v = Volume of the solution in liters.

so,

P/V. if T is constant.

PT. if V is constant.

PV is constant, if T is constant. are correct relations

Hence options A,B and D are correct.
