Answer:

A, D

Explanation:

Water evaporates into gas which requires an increased amount of energy.

sergiy2304 [10]
P1 = 5.7atm V1 = 26L
P2 = ? V2 = 6.5 L

By Boyles Law,
P1V1 = P2V2
5.7 × 26 = P2 × 6.5
By solving,
P2 = 22.8atm.

Salt dissolved in water is a solution, therefore _____.
saveliy_v [14]

Answer: Correct options are as follows.

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.

Explanation:

When salt is dissolved in water then it means that it is a physical change as salt has completely dissociated into ions but they are not chemically combined to the water molecules.

As a result, both salt and water will retain their chemical properties.

For example, NaCl when dissolved in water will dissociate as follows.

           NaCl \rightarrow Na^{+} + Cl^{-}

Only the particles of salt have evenly distributed in water.

And, when a components of a salt chemically combine with another substance then it will form a new compound.

Therefore, we can conclude that salt dissolved in water is a solution, therefore:

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.
