why does the ballon shrink when u put it in liquid nitrogen?

Question

i need detailed answer
thanks

Answer 1

The air inside gets so cold that it loses it's pressure and the atmospheric pressure crushes it.

Answer 2

You can get the same effect with just any other cryogenics gas like liquid Nitrogen, liquid Oxygen, liquid Argon, liquid Helium, etc. The only different is that with each type, the ballon shrink more or less depends on the boiling point of that gas.

Answer 3

The air molecules inside the baloon loose energy as they cool down. The way this manifests itself is that the air molecules slow down (E= 1/2 M v^2).

Because the air molecules are moving more slowly they "hit" the sides of the balloon less frequently and with less energy. This means there is a reduction of pressure inside the balloon.

The pressure outside the balloon is constant and so the volume of the balloon reduces until the pressures even out.

Answer 4

P*V = n*R*T

Pressure times volume equals two constants (defined by the type of gas molecule) times the temperature.

You can find this in most any chemistry book.

so lets manipulate the equation:
V (volume) = nRT/P

looking at this, you'll see that if the temperature drops in half then the volume will decrease in a proportion based on the characteristics of the gas. (assuming the pressure stays the same , which in the examply you gave... it does)

Answer 5

Because of Charle's law
There is an direct relationship between volume and temperature of an ideal gas.
As temperature decreses volume decrease... the atoms/molecules are moving slower and begin to attract each other causing the volume to decrease.

Answer 6

volume of a gas is proportional to its temperature,(as the temperature goes up the volume also goes up, and as the temperature decreases the volume decreases). liquid nitrogen its self is just a highly compressed state of the gas nitrogen that makes up most of the air we breath.

Answer 7

Pressure = volume/temperature.

Lower the temperature, and both the pressure and volume are decreased as well.
