A balloon is filled with helium. Its volume is 4.2L at 312.K. What will its volume in liters be at 285.K assuming no change in pressure?

Assuming pressure is constant, like you said, volume and temperature have a direct relationship. As temperature increases, volume increases; as temperature decreases, volume decreases. Setting up a algebraic direct proportion, you get approximately 3.84 liters for the balloon at 285 degrees K.

A balloon is filled with CO2 in the same room on the same day at the same atmospheric pressure a second balloon identical to the first is filled with O2 according to avogadro the experimenters?
the same amount of molcules in each A+
What causes a gas to exert pressure when confined in a container?
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
Explanation of blowing up balloon with carbon dioxide?
As the gas is pushed into the balloon the internal pressure increases, to reduce this pressure the rubbery material expands to increase the volume and ultimately reduce the pressure. Once the balloon is filled with CO2 and the knot is tied the balloon will probably sink this is because CO2 is more dense than air.
Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
If a balloon filled with hydrogen gas explodes upon contact with a spark a chemical or physical change?
It is a chemical process.
If you push on the sides of a filled balloon how does the gas pressure inside the balloon change?
Calucus
Why does a balloon change shape when filled with water?
The water produces hydrostatic pressure
If a balloon is filled with more air its pressure increases then why it is called an intensive property?
ntensive property of a balloon
Is Carbon dioxide filled with balloon a chemical change?
No. helium is released in outer air but does not lose or change its chemical formula
Why balloon filled with air brusts in heat or sunlight?
By heating the pressure in the balloon is rised and the limit of the resistance of the balloon envelope is exceeded.
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
If you apply pressure to a balloon filled with water will it pop and make a mess?
sometimes, depending on how full the water balloon is.
Why does a balloon filled with helium gas rise to a particular height and doesn't rise further?
That is because the Pressure inside the balloon caused by the filled pressure reached equilibrium at this point based on the height so can rise no longer.
Is balloons filled with helium a chemical change?
A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
If you push on the sides of a filled balloon how does the pressure inside change?
If the balloon is not encased or in restricted volume, then it changes its shape to accomodate that push but prutruding on the other side and the pressure remain same. However, if there is restriction for shape change, then when you push on the balloon, the volume decreases and therefore the pressure increases. A practical balloon, by the way, will behave between these two extremes. Pushing on one side and causing it to change shape definitely results in an increase in internal pressure. This is because the elasticity/tension of the rubber is the encased space.
While a balloon is being filled if the temperature of the air in the balloon decreases what happens to its volume?
volume decreases considering the pressure is constant
What do air particles do to keep a balloon inflated?
It's buoyancy - the same as a ship floating in water.In this case the volume of the balloon must weigh less than an equal volume of air.(That's done by using a lighter than air gas - hydrogen, helium, or just heated air.)
