Which of the following statements is true?
water is easily polluted because it can dissolve harmful chemicals.
when water freezes, it contracts and becomes more dense.
thermal pollution happens when cold water is released into an ecosystem.
adhesion describes a water molecule's attraction to another water molecule.

Water is easily polluted because it can dissolve harmful chemicals.

Water is capable of dissolving a variety of different substances in it, hence, it is called as universal solvent. It exhibit a polar arrangement of two elements named as hydrogen and oxygen. The hydrogen has positive electrical charge whereas the oxygen has negative electrical charge. This polarity is responsible for attracting different types of molecules. Hence, favors dissolution in water.

Therefore, water is easily polluted because it can dissolve harmful chemicals is the correct option.
