The change in air pressure between the floor and the ceiling in a typical room can be estimated using the hydrostatic pressure formula ΔP = ρgh, where ΔP is the change in pressure, ρ is the density of the fluid (in this case, air), g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height difference. Assuming a typical room height of 2.5 meters, the calculation would be ΔP = 1.2 kg/m^3 * 9.8 m/s^2 * 2.5 m = 29.4 Pa, which is approximately 30 Pa, thus the closest answer is 35 Pa.
