Re: nitrous in your car?

I agree with everything you wrote except the above statement.  How can the
Ideal gas law NOT apply?  Regardless of the state or amount of nitrous in
the tank, if you increase the temperature of the tank (without releasing
gas) the pressure is going to increase.  Remember, the tank exploded while
the car was sitting in the garage...the nitrous system was not actively
being used (other than the bottle heater, apparently).  Admittedly, there is
only a small volume of gas in a full tank of nitrous oxide (mostly liquid),
but even that small volume is subject to the Ideal gas law.
