Which statement is true of water? Water molecules attract hydrophobic substances. Water evaporates after absorbing small amounts of heat energy. Water’s hydrogen atom is slightly negative. Water molecules are polar. Water’s oxygen atom is slightly positive.

Option (d) is the correct answer.

Explanation:

Hydrophobic substances are the substances which hate water molecules. Whereas hydrophilic substances are water loving substances.

As a water molecule contains an electropositive hydrogen atom and an electronegative hydrogen atoms. So, there is a partial positive charge on hydrogen atom and partial negative charge on the oxygen atom.

Therefore, water molecules are polar in nature.

Also, water has high specific heat value that is, 4.186 . Therefore, in order to evaporate it needs to absorb high heat and not small amount of heat.

Thus, we can conclude that the statement water molecules are polar is true of water.

the dependant variable is spilled water

the independent is the heat
