We sit in the room with windows open. Then

Options

  1. Aair pressure on the floor of the room equals the atmospheric pressure but the air pressure on the ceiling is n
  2. Bair pressure is nearly the same on the floor, the walls and the ceiling
  3. Cair pressure on the floor equals the weight of the air column inside the room (from floor to ceiling) per unit
  4. Dair pressure on the walls is zero since the weight of air acts downward

Correct answer

B. air pressure is nearly the same on the floor, the walls and the ceiling

Step-by-step solution

Pressure of gas is app. same everywhere in the vessel
