Select all of the items that are true about a sample of water vapor at 101°c as it cools. a) its temperature will fall continuously until it condensed into a liquid. b) its temperature will fall steadily until reaching 100°c. c) the molecules of water gain potential energy. d) its temperature will remain at 100°c until all the vapor condenses.

Answer;

A) Its temperature will fall continuously until it condensed into a liquid.

Explanation;Steam or water vapor is the gaseous state of liquid water.  When water vapor above a temperature of 100 degrees Celsius is cooled, the temperature falls continuously, and it undergoes condensation at a temperature of 100 degrees Celsius and turns into liquid water.The change of state from gaseous to liquid state occurs as a result of latent heat of vaporization that the water vapor carries.
