IDEAL GAS LAW

1) What is the relationship between pressure and temperature at constant volume? At a constant volume, as the temperature increases, the pressure also increases.

2) Using this data, predict at what temperature the pressure will exceed 10 units If the pressure is 10.1 units, the temperature would be around 732 ° .

3) You may test this prediction but be sure to reset the experiment after the chamber breaks. At 738 °, the pressure was 10.17

*When the temperature is held constant, as the volume increased, the pressure units decreased.
Ratio: [4.75 volume: 13.0 unit]

(3.) Question 7.74
a. Increase in pressure. As the volume decreases, the pressure increases.
b. The same. The pressure stays the same when the volume & temperature is constant.
c. Pressure increases. At a constant volume, as the temperature increases, the pressure also increases.
(4.) What is the total pressure(mmHg) of a gas mixture containing argon gas at 0.25 atm, helium gas at 350 mmHg and nitrogen gas at 360 torr. (Hint: use Dalton’s Law of Partial Pressures).
*Dalton’s Law: a gas law stating that the total pressure exerted by a mixture of gases in a container is the sum of the partial pressures that each gas would exert alone.
*Partial Pressure: the pressure exerted by a single gas in a gas mixture.
