Boyle's Law Questions...?

Question

1. What happens to a filled balloon when the temperature remains constant and the air pressure in a room drops?

2. Define IDEAL GAS

3. Define PARTIAL PRESSURE

Answer 1

1. The balloon will expand.

2. It's a gas that follows all gas rules exactly and without exception. No gas really does this; it's a theoretical thing. However, most gases behave "ideally" at low pressures.

3. In a mixture, each substance contributes to the total pressure of that substance. In atmospheric air at sea level, for example, multiple gasses are involved: nitrogen, oxygen, carbon dioxide and water are the primary players. Together, they exert a pressure of about 750 torr at sea level. Oxygen contributes about 160 torr of that total - ie, the partial pressure of oxygen at sea level is 160 torr.

Answer 2

1. The balloon expands.

2. Any gas which follows Boyle's law, pv = k. Real gases do not exactly follow it; it is only an approximation. (There is a technical explanation, but this is the essence of it. If you want the technical def go to the source I listed below.)

3. Partial pressure of an ideal gas, in a mixture of gases, is what the pressure would be if the same amount of that gas were the sole occupant of the same volume as the mixture. As might be expected, the sum of the partial pressures of the gases in the mixture will be the pressure of the mixture at that volume.

Answer 3

1. If temperature remains constant, and pressure drops, then the balloon would increase in volume. pv=nkt

2. An ideal gas or perfect gas is a hypothetical gas consisting of identical particles of zero volume, with no intermolecular forces. Additionally, the constituent atoms or molecules undergo perfectly elastic collisions with the walls of the container.

3. Partial pressure is the pressure one element or molecules contribute to the total pressure of the atmosphere.

Answer 4

1) The balloon expands....

PV = nRT. since n, R and T are all constant....

P1V1 = P2V2

V2 = P1V1/P2. and since P1>P2, V2>V1.


2. In an ideal gas, the interactions between molecules is insignificant.

3. Partial Pressure is the pressure exherted by one gas in a mixture og gasses. It is equal to the total pressure of the mixture times the mole fraction of the species in question.

Answer 5

1.The ballon expands. Depending on the extent on drop in pressure it might break up also.
2.We have the universal gas equation.
PV=MRT
where
P=pressure
V=volume
M=mass
R=universal gas constant
T=temperature in Kelvin
A gas which obeys this law is called ideal gas.
3. When we have several gases in an enclosed vessel, each gas exerts its own pressure on the vessals walls. Call them p1,p2,....pn
Total pressure in the vessal=sum of all partial pressures=sigma[p1,p2...pn]
This is the concept of patial prssures.

Answer 6

specific it does. The temperature will strengthen additionally as a results of fact, the quantity of the ball does not shrink in share to the rigidity strengthen. for this reason the ball turns into extra sturdy (extra employer) as a results of fact the rigidity will strengthen (as does the quantity as much as a element the place the ball casing can no longer strengthen). it relatively is going to be the mixed gasoline regulation it is derived from the mixture of Boyle's regulation (P1/P2 = V2/V1), Charle's regulation (T1/T2 = V1/V2) and gay Lussac's regulation (P1/P2 = T1/T2). mixed gasoline regulation P1V1/T1 = P2V2/T2. EDIT: To the skeptics...have you ever felt the tip of a hand pump whilst pumping up a ball or motorbike tire ? ... It gets relatively warm as a results of compression of the air. In Boyle's regulation, Temperature is persevering with. i believe that my answer shows that Boyle's regulation IS violated as a results of fact all parameters are changing and that Boyle's regulation won't be in a position for use....it relatively is the mixed gasoline regulation it is required.

Answer 7

1. it will expand because their is less pressure around it

2 and 3 would have to look up, mabye try wikipedia at
