Question

Classify each situation by the appropriate equation that quantifies it.
A. A container of ammonia cleaner is stored in the janitor's closet off a lecture hall after being used for cleaning at night. The container has a very small hole in the lid. The next morning, the entire lecture hall smells of ammonia. How would you calculate the speed of the ammonia molecules as they move into the lecture hall?
B. The pressure on a tire pump is measured. The handle of the pump is pushed down as far as possible. After this, the pressure reading on the gauge is taken again. How would you calculate the final pressure?
C. When the burner under a hot air balloon is ignited, the balloon expands. What equation would you use to calculate the expanded volume of the balloon?
D. A front-end collision causes the airbag in an automobile to deploy through the reaction of sodium azide, which produces nitrogen gas. How would you calculate the amount of sodium azide needed to fill a standard-sized airbag with nitrogen under standard temperature and pressure (STP) conditions?
E. Aerosol cans carry a warning not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant. If the residual pressure in the can is 1.31 atm when it is sitting on a shelf near a furnace, how could you calculate the pressure when the can is placed on top of the furnace, where the temperature reaches the boiling point of water?
F. In an automobile engine, at the end of the upstroke, the piston reaches its maximum height within a cylinder of exact dimensions. At this moment, a precisely measured mixture of fuel and oxidant ignites to form gaseous products. If the ignition temperature is known, how could you calculate the pressure inside the cylinder just before the piston starts to move downward?
Match these situations with their corresponding equations: 
1. P1V1 = P2V2
2. U = √(3RT/m)
3. (T1/V1) = (T2/V2)
4. (P1/T1) = (P2/V2)
5. Others

A: The root mean square velocity of a gas is given by.........U=square root:(3RT/m)
B:Since increase in pressure leads to a change in volume, here we use.....P1V1=P2V2........where pressure and volume are related.
C:using the equation (T1/V1)=(T2/V2), we get the result as here volume and temperature are related.
D:Here you need to deploy simple Stoichiometric equations...........so here -------------- others.
E:here pressure is related to temperature ...........so we use (P1/T1)=(P2/T2)...............pls correct the question in this regard.
F:We can use here .................(P1/T1)=(P2/T2).............taking P1 and T1 at STP conditions

im pretty sure A,B are P1V1=P2V2 C is (T1/V1)=(T2/V2) D is PV=nRT E,F are (P1/T1)=(P2/V2) im not sure about f part b is 1.90 atm
