Will a balloon deflate faster in warm or cold temperatures?

Answer 1

A helium balloon of the same material will deflate faster.

Helium molecules are smaller than those in regular air, so they'll seep through tiny holes and imperfections in the skin of the balloon faster.

When using the standard PIN analysis - both helium and common air balloons were found to deflate at the same rate.

To the naked eye, both balloons stuck with a pin deflated with a pop.

However, if the balloons are left intact, the helium balloon will deflate faster. This is because the helium molecules are small enough to pass through the rubber balloon, and they gradually leak out.

Answer 2

In theory, smaller molecules (such as He2) should escape from a balloon faster than larger ones (such as CO2), because they can fit through smaller pores or imperfections in the balloon's material. If you have ever compared helium balloons and air-filled balloons, you have almost certainly seen the helium balloons do this.

In practice, however, standard latex balloons filled with carbon dioxide deflate much faster than ones with either air or helium. Presumably an interaction between latex and carbon dioxide either allows the gas to escape, or consumes it in a reaction.

Answer 3

Rubber. It doesn't hold the gas in as well as the Mylar does.

Answer 4

depends on the temp of air inside the baloon

Answer 5

Latex.
