How is it possible fro one tank of helium to fill 700 balloons

[From: ] [author: ] [Date: 11-05-06] [Hit: ]

b) Helium expands more in hot weather and less in cold weather-Helium is a gas, and gases can be compressed. So unbelievable amounts of helium can go in that one tank. Its metal so it wont explode.......

How is it possible fro one tank of helium to fill 700 balloons?
Also, Why is more gas needed to fill helium balloons on a cold day?

PLEASE PLEASE PLEASE HELP!!! Thank you :P

a) It is pressurized in the tank, so the volume of balloons it can fill exceeds the volume of the tank
b) Helium expands more in hot weather and less in cold weather
