connect.htm -G e Connect 2 Lecture Assignment ndicate whether each statement is true or false regarding pressure of gases . Gases move from an area of lower concentration to higher concentration. [Fabe 2 Dalton's law states that the total pressure of a gas is the sum of pressures of each gas True 3 lfasingle gas represents 60% of the total gas, its partial pressure will be 60% of the totalpress re kb eco 4. I1 the concentration of oxygen in the alveoli is greater than the concentration of oxygen in the blood, oxygen will diftuse out of the blood. Cick to select) 5. Typically, carbon dioxide concentrations are higher in the blood than in the alveoli, so carbon dioxide diffuses from the blood to the alveoli. [Cick to select) Prev 55 of 65Next

Explanation / Answer

1 moving from lower to higher concentration is known as diffusion. normally the gases undergo osmosis. it undergoes diffusion when present with water. so it is false.

2. daltons law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. so the statement is true

3 true according to daltons law

4. false as oxygen moves out from alveoli to blood.

5. the statement is true.carbon dioxide diffuses from blood to alveoli.
