3. Balloons are filled with equal volumes of different gases and are allowed to sit at room temperature. The balloon filled with which gas will last the longest (deflate the slowest)? (a) HCI (b) Ne (c) Xe (d) Ar (e) they will deflate at the same rate 4.If gas A has a MW of 20 and gas B has a MW of 80 which of the following is true. (a) A will diffuse four times as fast as B (b) A will diffuse twice as fast as B (c) B will diffuse four times as fast as A (d) B will diffuse twice as fast as A (e) since diffusion rates depend only on temperature, they will diffuse at the same rate
