We had spud surprise t'other day. It included boil int bag white fish in butter source. The box tells yer to pop the bag before cookering int microwave. Eye has always done this but wondered iffit were necersary. So this time eye cookered it wiv no hole. Bad move. The bag expanded and split so it had its own hole near the bottom. This meant the source sprayed oot as the bowl turned round.

Isn't that why it's called "pop, plink, ping" or summat like that?
Boyle's law is why it happened 🤣 🤣 🤣 !
(Sorry about the sauce though!:()
 
Took me years to get Boyles law, and temperature was never in the equation (P1 x V1) = (P2 x V2) that's it. init?

J
That IS it but it assumes constant temperature.
If you heat a gas in a constant volume, the pressure of the gas inside it will rise in direct proportion to the temparature.
Which is why a piston in a car engine flies down (i.e. volume increases) when the mixture explodes. The volume increases as the temperature and therefore the pressure increases.
I believe the equation with all three in it is
P1V1/T1 = P2V2/T2
