A colligative property of a solution is one that depends 1. on the identity of the solute and the concentration of the solution. 2. only on the concentration of the solution. 3. only on the identity of the solvent. 4. on the identity of the solvent and the concentration of the solution. 5. only on the identity of the solute.

The correct answer is option 2.

Explanation:

Colligative property is defined as property which depends upon only on the numbers of particles of solute dissolved in definite amount of  solvent, It do not depend on the nature of the solute.

For example : NaCl solution with 0.4 molal will show same colligative properties as a that of the glucose solution with 0.04 molal concentration.

The following are the examples of colligative property:

1. Relative lowering of vapor pressure.

2. Osmotic pressure

3. Elevation in boiling points

4. Depression in freezing point

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
