Question

Due to ______________, water takes longer to go from a liquid to a gas if NaCL (a solute) is added.

Select one:

the non-polar covalent bonds

the heat of fusion

the surface tension

the cohesion

colligative properties

Answer 1

Due to colligative properties, water takes longer time to go from a liquid to a gas if NaCl (a solute is added).

With addition of NaCl the concentration of ions in the water gets increase results in changing the colligative properties of the solution. As a result boiling point of water also gets increased thereby it taking longer time from a liquid to a gas with addition of NaCl salt.
