need a laugh

[solarman216]

here I am bored to tears with a pulled back and getting pissed.

So Question 1
Can a solid burn?

Question 2
if water did as most other stuff does and got denser when frozen (ie heavier) instead of lighter, would we humans be able to survive on earth,

answers on a post card please,

OK on here will be good,

Rick

To help you out..
What solids burn?
Wood, Coal, Paper, ....

Ice gets less dense as it gets colder, that's why it floats on water.

Water has it's maximum density at 4C that's why fish can survive when the water above them has turned to ice.

sorry but those items in there natural state do not burn, and yes ice floats so what if it did not? Rick

Well all those Souls on the Titanic would not be dead

I would presume that if all the Ice sank, the water levels would rise, drowning most of us.

As far as burning a Solid, the thing that comes to mind is Wire wool, it's made from Steel, which is a solid, just thin strands, but it burns very easily.

1) Doesn't the said solid need oxygen to burn? And as there is no oxygen within a solid then no. Or the solid heats up to a gaseous state and appears to burn.
2) Ain't got a chuffing clue.

OK Clive you have the second one, yes if all the ice sank there would be very little land mass to support life, if at all.

Don Simon yes only a gas can actually burn, so everything can burn but has to attain a temperature to turn it into a gas first, Rick

Rustic that is just too complicated on a Friday night, and with the likes of Clive and Don my little forray did not last too long did it, will have to think of some more.

How about a prop shaft, is it constant velocity? Rick

OK, I put a lot of thought into this last night... sad I know... but I guess the first issue, is how you define a solid. If you are saying it has to be a "Pure" material, then that cuts the number of available things down considerably. E.g, You can't have brass, but you can have Copper, Tin, and Zinc. If this is the case, what about Magnesium, it is a solid, can be melted into a liquid, but will combust, even burning in non-oxygen environments. So surely this is a Solid that can burn?

The bit I find ironic is, it also used to fireproof wood???

Did you know, water is special, without it's properties, I doubt life would exist.
It is, as far as I am aware, unique.

It can exist as a solid, a liquid and a vapour at the same time...
At a certain temperature and pressure.
It's called the triple point of water.
The temperature on the graph is show in degrees Kelvin, to convert to Celsius,
approx 273 K = 0 C

A good friday night discussion.
