Chemistry PLEASE HELP!!!!!?
Any ideas or suggestions would be great!! =D
Answer:
gas law is p.V=n.R.T
having in mind that the balloon is sealed, and that the pressure inside remains constant, when it goes up, the pressure goes down, as well as the temp. since apparently the pressure decreases more rapidly than temperature, making the balloon expand, if i were full filled, it would have exploded.
Not sure what the kinetic theory is.
but all i can say is that a gas' volume can change depending on temperature or pressure.
as you climb higher distances in the atmosphere, the air pressure drops. for example; at sea level, the atmospheric pressure is 760 mmHg but if you climb up the mountain Everest, you will see that the atmospheric pressure has decreased to (let's say) 730 mmHg.
So, if you fully inflate the balloon, it will explode at a level where pressure is too low. that is, inner pressure of the baloon will still be 760 mmHg, but the pressure outside will be lower (like in the example of Everest ). But if you half fill it, it will only expand not explode...
Kinetic theory gives us the gas laws. But, if one considers that gases are rigid spheres in constant motion, then a half-filled balloon at 1 atmosphere pressure will expand when it rises to higher altitudes because there are fewer rigid spheres pushing against the outside of the balloon.
From the general rule of gases we have:
PV=nRT
where,
P= pressure of gas
V=volume of gas
n=number of moles
R=international constant of gases
T= absolute temperature
if we assume that the temperature is fixed, then in upper parts of atmosphere because of low pressure the volume of balloon will be increased and if it was completely filled, it would explode!
Hope this helps.
