Heat of solution is always positive.

Solute Potential of a solution is always

Water potential of a solution is always

For real values of 'x' , Which of the following is/are always positive? (a) sin(cosx) (b) sin(sinx)

Assertion: The chemical potential of pure water at normal temperature and pressure is zero. Reason: In solution, value of water potential is always positive.

Assertion (A): pH of neutral solution is always 7 . Reason (R) : pH of solution does not depend upon temperature.

$ Soil solutIon is absorbed by all the parts of a root . ! Soil solution is always of a high concentration.

Assertion: Distance is a actual length of the path but displacement is a shortest distance between initial and final position. Reason: Distance is a scalar quantity and it is always positive but displacement is a vector quantity. It may be positive, negative or zero.

Select correct statement : a. Solution has more molecules randomness than a pure solvent. The entropy change between solution and solid is lager than the entropy change between pure solvent and solid. b. Heat of fusion of solution are positive c. Both a and b d. None of these

Statement-1 : The mass fraction of solute in a solution is always greater than its mole fraction Statement-2 : Mole fraction of solvent in an aqueous solution of ethanol must be greater than that of solute

Determine the value of 'a' so that the expression x^(2)-2(a+1)x+4, x in R is always positive.
