what happens to the volume of a balloon when it is taken outside in a cold winter day?

The volume should decrease because the colder air causes the gas molecules to lose kinetic energy and slow down.  This makes the air pressure in the balloon lower and the balloon's volume is reduced.

it has nothing to do with the air in the atmosphere its the air that fills the balloon up. when its hot the ballon goes up as it cools it goes down

Assuming the container was rigid (like a tin) and completely empty (i.e., a vacuum) before you put the air in, the container would be full, because gasses expand to fill the space that's available, so the container would hold 2 litres of air that would be less dense. \n\nIf the container was flexible (like a balloon), the air pressure outside it would collapse/squash the container until the pressure inside was the same as the air pressure outside, so it would be still be full, but it would contain 1 litre of air that was at normal density.

This is similar to asking why gravity doesn't affect boats. It does, but buoyancy keeps them above water. Similarly, if you push a hollow rubber ball down to the bottom of a pail of water and simply release it, it will pop back up to the surface.\nThe helium balloon is just being pushed up by the relatively higher air pressure under it. See the sources for a detailed calculation and a diagram of the pressure situation.

it depends on whether or not enough people request it.  \n\nMost likely it will snow ALOT

i dunno but it'll be cold

The question isn't sick, its science.  In the cold our musels contract making them go up.

There are a couple of things you need to think about so you can work this out for yourself. \n\n1. Gases expand when they are heated. This is easily seen from the ideal gas law, PV=nRT, where P is pressure, V is volume, n is number of moles, R is a constant and T is temperature. Most gases roughly follow this law. As T increases, so does V, at constant P (of course, in the case of a balloon, P does not remain constant). \n\n2. When the volume of a gas increases, its density D=mass/V  decreases.\n\n3. By Archimedes principle, the buoyant force on an object is equal to the weight of the fluid displaced. The net buoyant force is the difference between the buoyant force on the object and the weight of the object. \n\nSo in the case of your balloon, if it displaces air of greater density (since it is colder), then there is going to be a net buoyant force upwards on the balloon. The weight of the air of density Da displaced by a balloon of volume V is V*Da*g, where g is the acceleration of gravity. \n\nI could go into more detail, but you might enjoy working this out for yourself. If you need more help, then ask.

Take a balloon and blow it up partially.  Weight the balloon and submerge in a beaker of water (so it doesn't float).  Gently warm the water with a burner or hot plate.  The balloon will get bigger as the water gets warm.  Then you can remove and submerge into ice water to see it shrink.\n\nThe volume of a gas is directly proportional to the temperature of the surroundings.\n\nAnother idea: Fill the bottom of a pop can with water.  Heat the can using a hot plate.  Allow time for most (but not all) of the water to boil away into steam.  Using tongs, pick up the can and place in ice water.  The can will collapse!  For a louder effect, use an old metal gas can.

Hahahahahahaha, how amusing the previous anwers are.\n\nThe balloon would continue to rise in the atmosphere until it reached a height where the pressure inside the balloon was equal to the pressure outside the balloon...then it would remain at the same height, moving in the wind, maybe slightly up and down due to thermals...until it burst !

Tempreture effects the volume and pressure of the gas inside the balloon.\nAccording the this formula (Pressure . Volume)=(nR)(Temp)\nby increaseing temp you are gonna have smaller pressure and volume(thus smaller balloon) and by increasing temp, you are gonna have higher pressure and volume(thus bigger/stiffer) balloon.  \nKeep in mind the effect of temp on the volume and the pressure of the gas or liquid inside the balloon depends on many factors such as the type of gas or liquid, what the balloon is made of and...

you should observe an initial volume 1V, and xV when the balloon had rise, at sea level atm pres. is 1 and at x is 0.8, so you do\n 1V -  1\n xV - .8\nas all inverse proportions you do the math as follows\nxV =  1\n1V    0.8   \nx = 1/0.8\nx=1.25 which means 125%\nso volume increases by a 25%

Thats a difficult question. It all depends on air pressure, wind, temperature, humidity, distance of the clouds above the earth. Velocity of the snowflake. Mass of the snowflake. It's really dependent on the situation and the composition of each individual snowflake. No two conditions are the same.

it all depends on what Temperature is acting upon.  If your talking about a solid, no, not really, if it does, it is negligible.  However, Temp. does affect the density of liquids, most liquids become more dense as temp. get colder, and less dense if the temp gets higher.  If you are talking about gasses, then the temp will affect both volume and density. think of a balloon. If you put a balloon outside in the winter, it will become smaller.  This is because the density of the air inside goes up and the volume goes down.... \nThe formula to determine what happens with a gas is PV=nRT, whereby P=the atmospheric pressure, V=volume, n= the #of moles of a gas R=is the ideal gas constant and T=temp... hope that helps.

A gas burner heats air inside the balloon and as the air becomes warmer it becomes less dense or lighter per unit of volume, compared to the surrounding air. The differance in the two air densities causes the balloon to float like a cork in water.  This is the reason balloonists launch their ballonons in the early morning when the air tempature is cooler.  The cooler the  outside air the less heat is needed in the balloon to get it off the ground saving fuel for a longer flight.

A full baloon will weigh more if you are filling it with room air.  The air under pressure will mean there are more molecules in the balloon.  More molecules of 'x' weigh more than fewer molecules of 'x'.

If it is 0 deg Centigrade i.e. 32 deg Farrenheit and double the cold i.e. 16 deg F mening -8.9 deg Centigrade
