partial pressure

Quote:
partial pressure n.

The pressure that one component of a mixture of gases would exert if it were alone in a container.

So what I was talking about was a gas which was 100% O2 at a given pressure (not necessarily atmospheric) and all of that pressure is therefore exerted by the oxygen.

Come to think of it it's not a good or conventional way of expressing it but it is a quick way; 100% O2 at any given pressure would have been better.

Were'nt we talking about dynamite?

How much dynamite would it take to destroy a small, 3 storey house? Would it depend on where/how it was placed?

It certainly would. You'd have to take into account the structural design and materials of the building's supporting walls and floors, and also the volume of the space into which the dynamite was installed, and how quickly the gases could get out of that space.

I've only ever managed to explode a catering-size can of baked beans with explosives, so that's probably not much help. If you're wondering, it made an interesting pointilliste spatter effect on the side of my friend's house, but for some reason his mother wasn't convinced of its artistic merit.

At the other end of the scale, research undertaken by physicists from the Centre for Explosion Studies at the University of Wales in Aberystwyth concluded that an explosion of the 2,500kg of gunpowder Guy Fawkes was found with would not only have destroyed Westminster Hall and the Abbey but would also have caused severe structural damage to buildings two-thirds of a mile away. It isn't certain that the gunpowder would have exploded at all, however; some historians believe that it had decayed chemically so as to be no longer dangerous at all.

Many comic pictures appear in my mind. Imagine the phone call to the buildings insurance people to get a quote: "...and what's the nature of your company's work?". Imagine the exam room at the end of term.

Fred has some first-hand experience of blowing up Houses of Parliament, I believe...

Surely they would have to change location a lot

I'd be very wary about going too near the party poppers at the Christmas party though.

This suggests a nice new thread, which I will now start.

good for you, but now this thread will lose all its customers. That was a harsh business move, you bill gates like person.

I would normally recomend a longer length of wire, but if you lack excitement in your life.

I watched a piste-manager one morning skiing casually along a ridge lighting sticks of (something or other) from his Galoise and tossing them nonchalantly into the potential avalanche drift which he'd coolly skied over a couple of seconds before.

Now that's a man's breakfast.
