When heat is constantly supplied by a burner to boiling water, then the temperature of the water during vaporization:(a) rises very slowly(b) rises rapidly until steam is produced(c) first rises and then becomes constant(d) does not rise at all
Correct Answer: (d) does not rise at all
Explanation: The temperature of the water during vaporization remains constant because the heat is used in overcoming particle-particle attraction forces, which in turn keeps the temperature constant.
