Answer 2

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.
