Telephone lines carry a small voltage, so I would assume the lightning may cause a surge. However I'm not sure if that is what you are after.

Ok. Here is what I did. First, as you said, I worked out the number of moles of helium needed to fill each balloon to 3L. Assuming that 1 mole is 24.47L at 25oC (298K) I calculated that each balloon needs 0.12moles of gas to fill it. I then used PV=nRT to work out that there are 11.8...

Ok I understand now. Thank you for explaining that.

What equation did you use to work that out?

Homework Statement How many 3L balloons can you fill from a 20L tank of helium at a pressure of 14.4atm. Homework Equations Boyle's Law: P_{1}V_{1}=P_{2}V_{2} The Attempt at a Solution \frac{14.4atm\times20L}{1atm}=V_{2} I then divided the answer to thank by 3 to get the amount...
