Infiltration in a house in the winter where T = - 25° C occurs even when there is no wind due to the difference in the air density between the inside and outside of a house. For an inside temperature of 22° C, the density difference is nearest:
(A) 0.207 kg/m3
(B) 0.224 kg/m3
(C) 0.241 kg/m3
(D) 0.288 kg/m3
