Combined Gas Law Problems
P. V.T2 = P2V,1,
1) If a gas initially has a temperature of 600K and a volume of 2.1 liters, what will the volume of the gas be if
cool it to a final temperature of 340K? Assume the pressure and amount of gas remain constant.

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
