Question

6. Mercury metal is a liquid at room temperature. As heat energy is added to liquid mercury, the
temperature rises until it reaches its boiling point at 357 °C. The temperature remains at this
level until all the liquid has changed to gas, after which the temperature of the gas begins to
rise again
Explain why the temperature of the mercury did not rise while it was boiling.
7. Explain what happens to the mercury atoms due to the added energy during the time in which
temperature stays the same.

Answer 1

The heat added to the mercury while it changes to vapor only breaks the interatomic bonds in mercury but does not raise its temperature.

One of the effects of heat is that heat raises the temperature of a body. Usually, when heat is added to a body, the temperature of the body is expected to rise steadily. This is the case when heat is initially added to liquid mercury.

The temperature rises until such a point that there is no further rise in temperature when the mercury attained its boiling point. This is because, the heat supplied at this point goes into breaking the interatomic interaction in mercury causing the liquid to change to vapor. This heat is called latent heat of vaporization. The temperature continues to rise after vaporization is complete.
