If equal number of moles of three different gases are placed in separate sealed identical flasks at the same temperature, which flask will have the highest pressure? A. the gas with the higher molar mass B. the gas with the lower molar mass C. the gas that was placed in the flask first D. neither, the pressure will be the same in each
When volume is increased , why does pressure decrease? A. the temperature increases B. the pressure does not change C. there are more collisions D. there are less collisions
When a weather balloon increases in altitude, what will happen to the balloon if the atmospheric pressure is constant? A. It will get larger B. it will get smaller C. it will stay the same D. it will explode
Why does a balloon on the top of a flask start to inflate when the flask is placed on a hot plate? A. gases expand when heated B. some gases only react at high temperatures C. the pressure of the gas increases when volume decreases D. solids require heat in order to change into gases
As the number of moles of a gas increase, the _____ increases in a sealed container. A. volume B. temperature C. boiling point D. pressure
If pressure and temperature are both allowed to change, then decreasing volume _________________. A. increases pressure and temperature B. decreases pressure and increases temperature C. increases pressure and decreases temperature D. decreases pressure and decreases temperature *remember gas law apparatus!
Memorize and Know H ow to Calculate with… Boyles Law P 1 V 1 = P 2 V 2 Charles’s Law V 1 /T 1 = V 2 /T 2 Gay-Lussac’s Law P 1 /T 1 = P 2 /T 2 Combined Gas Law P 1 V 1 = P 2 V 2 T 1 T 2 Ideal Gas Law PV=nRT, R will be given…make sure you match units!Partial Pressures (with pressure, moles and percent)PT = P1+ P1+ P3Mole fraction X total pressure = partial pressure of gasPercent converted to a decimal X total pressure = partial pressure of gas
