Why do balloons deflate in cold weather?

Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.


When the temperature of the gas changes from cold to hot the amount of pressure is .?

In a closed system the pressure is higher.

Why does a balloon deflate in cold air and expand in hot air?

Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.


Cold drinks are bottled under a carbon dioxide gas pressure greater than 1 atmosphere why not more gas or less than that gas?

1 atm pressure is considered as standard and is atmospheric pressure at sea level.


In a closed containerwhat effects does pressure have on a gas volume and density?

The gas pressure in a closed container increases with volume and increased temperature. Likewise, the pressure will decrease with decreased temperature.


Why does a CO2 cylinder feel cold after it's launched?

As the gas quickly leaves the container, the pressure and the amount of gas inside decreases. With less gas, the heat decreases.


What does boyles law say about the relationships between the pressure and volume of a gas?

pressure will decrease when its cold and increase when hot just as the particles will work===========================Answer #1:It says that their product is proportional to the absolute temperature of the gas.


What happens to gas as the temperature rises?

when any gas is expanded, it's pressure would drop and the temperature would drop as well resulting with cold atmosphere.


Gas changing in to liquid?

a gas turns into a liquid when a hot gas (such as your breath) hits a cold surface (Such as a cold window) The gas suddenly gets cold and forms little liquid molecules (Which in my examples case is water). This process is called condensation


How does a refrigerator or freezer work to keep things cold?

Both the refrigerator and the freezer have fans to keep it at cold temperatures. PV=RT; A compressor raises the pressure of the gas volume V and temperature rises. A fan blows away the heat into the room. Then the gas pressure is dropped in the refrig cold room and the temperature drops in the cold room, PV=RT. The heat in the cold room heats up the gas and the volume goes to the compressorr again, ec,etc,etc.


What happens to the pressure of gas in a cold day?

well is your are talking about gas in the car i dont know sorry. :( But if you're talking about A GAS it will turn into a liquid then a solid. Hope i can help you.
