What change takes place when a liquid absorbs heat energy without increasing its temperature? a. the pressure increases b. it vaporizes c. it solidifies d. the volume decreases

B.

When water is heated, it evaporates.

Option (B) is the correct answer.

Explanation:

When a substance absorbs energy then molecules start to move from their initial place and they tend to slide past each other. As a result, phase change occurs.

A reaction in which reactants absorb energy are known as endothermic reactions. In this case, energy of products is more than reactants.

Therefore, when a liquid absorbs energy without increasing its temperature like ice melts at room temperature, then the liquid will evaporate.

the answer is either b or c
