how does a balloon get smaller in the freezer?

i know!\n\nas temperature decreases, volume decreases. its part of the kinetic molecular theory.\n\nthe gas particles move slower because they lose energy as temperature decreases so they don't exert as much force on the walls of the balloon, so the balloon shrinks.

The density will decrease.  This is because heating the gas will cause its pressure to increase.  The rubber (or whatever fabric the balloon is made of) will respond by moving outwards.  Therefore the volume will have increased and, since the mass of the gas will not have changed, it density will decrease.  The actual amount by which it decreases will depend on the elasticity of the fabric.\n\nIt's much easier to quantify the decrease if you are dealing with an open-necked balloon (such as a hot-air balloon), as the density of the gas is, to a fairly close approximation, inversely proportional to the absolute temperature.  So, if it is heated from 200°C (473K) to 300°C (573K), its density will decrease by a factor of 573 ÷ 473  =   1·211 (or, its density will become 0·825 (82·5%) of what it was before).

cryogenic freezing takes the object to absolute freezing (i.e. not just cold as in -20°).\n\nAbsolute freezing is -273.15°C (or 0° Kelvin)\n\nAt this temperature atoms completely stop moving and therefore stop aging. Anywhere above this temperature, then atoms still move, even if it is a slight little bit.

All gases get denser as they cool. Air in a balloon would also deflate if it gets cold. The gas in the balloon would expand if the balloon got hot.  Not to get too complicated, but colder temperatures make the molecules of the gas get closer together, which makes the balloon shrink.

Due to sublimation, it will weigh slightly less. However, in a closed system (say you sealed the cup in an airtight box and weighed that before and after the ice melted) there would be 0 change in mass due to conservation of mass/energy.

Surface tension. The tape holds the balloon in place.

if u really want to get an answer to this question, u need to be more through when asking it. hello? i mean seriously, we dont know anything around the experiment you are working on. so take the noncharged part of the balloon and put it next to the cereal and paper. what do u think will happen. something will and if you did it then you would know.

As the air pressure decreases around it, the air, if contained in a flexible enclosure, would expand, pushing the sides of the container outward. IE: a balloon getting bigger. But I'm not sure what you mean by a "parcel" of air.

Density= Mass/Volume.  When water freezes, its volume increases. This is why a frozen bottle of water expands to the point of bursting. By the formula, if volume increases and Mass stays the same, then the value of density decreases.  Thus, this is why ice floats and is less dense than water.  When the ice melts, the reverse happens in that its volume decreases and again by the formula, density will increase.   Tahdaaaa!!

ok, guys.  both v_dawg and quicksilver are right.  when water makes a phase transition from liquid to solid (freezing) it expands in volume; that's why bottles filled with liquid will crack in the freezer.\n\non the other hand, if you leave it sitting there for a while, there will be a slow phase transition from solid to gas (sublimation) and over weeks-months the ice cubes will noticeably shrink in size.

if both are frozen, none is colder than the other\n\nbut of course if you open the bags and leave the peas out, the small peas will heat up faster because of the higher surface area.

it has more to do with the differant tempatures\nto put a light in the freezer you need to shield it from the frozen tempatures\n\nin the fridge this is nota prob since tempatures are above 32 deg fahrenhiet

you do the experiment yourself places a cup of cold and hot water in your freezer, the hot water will freeze first, the\nhotter the water the faster it will freeze

as the temp goes up the molecules of gas move faster and collide more often with more energy into the balloon increaseing pressure and expanding the balloon.  As it cools the opposite happens.  Draw your own diagram!

yes you can freeze a water balloon

Most of the water molecules in the air in your freezer have sublimated to a solid state inside. Therefore, there are less water molecules in the air making it less 'humid'.

The balloon rises in atmosphere and remains intact till the point when its internal pressure is lower than the atmospheric pressure. At higher altitude where the atmospheric pressure is lower and the pressure inside the balloon is higher, it bursts as the rubber cannot withstand the internal pressure.
