could you help me with this question

thank you

a) What are the adverse effects of excess moisture on the wood and metal components of a house and the paint on the walls? b) How does the condensation or freezing of water vapor in the wall affect the effectiveness of the insulation in the wall? How does the moisture content affect the effective thermal conductivity of soil? c) Moisture migration in the walls, floors, and ceilings of buildings is controlled by vapor barriers or vapor retarders. Explain the difference between the two, and discuss which is more suitable for use in the walls of residential buildings. d) Why are the insulations on the chilled water lines always wrapped with vapor barrier jackets? e) Consider a tank that contains moist air at 3 attn and whose walls are permeable to water vapor: The surrounding air at 1 atm pressure also contains some moisture. Is it possible for the water vapor to flow into the tank from surroundings
