When a liquid is heated at its boiling point,the
A)ionic bonds are broken,allowing sublimation to occur.
B)temperature of the liquid decreases.
C)temperature of the liquid remains the same as long as any liquid is present.
D)temperature of the vapor phase decreases.

Question

Quizplus · Accepted Answer

At the boiling point, the temperature of the liquid remains constant as long as any liquid is present because the heat energy is being used to convert the liquid into the gaseous state (vaporization). Once all the liquid has been converted into vapor, any additional heat will raise the temperature of the vapor phase. The other options are incorrect as ionic bonds are not present in all types of liquids, the temperature of the liquid does not decrease at its boiling point, and the temperature of the vapor phase increases as more heat is added.
