I wrote it myself. I was having a random chat with a guy at work and I said something about understanding electricity being a black art (I'm a clanky by nature). Hs siad "no, water's the weird one" and made the point about it conveniently boiling at 100deg C etc, he had a point and it got me thinking and I expanded on it. It's in my 'book' of random thoughts (and rants). Inspiration comes from (love him or hate him) Jeremy Clarkson and the likes of Rhod Gilbert.

But. water does not always boil at 100deg C neither does it always freeze at Zero.

 

pressure and catalysts have a lot to do with it.

 

 

Just like Women.

Its about the metrics too...

 

The energy required to heat 1gram of water by 1 degree, is 1 calorie... 1litre of water is 1kg... its not incidental that all these figures coincide. It's better than the American alternative and supprising they manage to get anything done with all those awkward conversions going on.... Probably why they struggle to get 300bhp from a 8 litre engine (or what ever the cubic inch conversion is)

But that is the definition of a calorie...

[mini93]

Indeed, but its working joules of energy too.

[Vinay-RS]

yeah but a joule is a Nm. and the specific heat capacity of water at constant pressure and room temperature is 4.18J/gK

Argh why are we suddenly doing physics? nah just jokin, I like physics

There's always one....

This conversation takes me back to school when we had to set fire to a peanut. Something to do with joules. I can't quite remember what though

[MrBounce]

Set fire to the peanut, see how much it raises the temperature of the water in the beaker above it, work out how much energy in said peanut. Or something like that anyway. It was 30 years ago for me!!

 I remember that experiment. I also remember a girl (and I am not making this up) called Hazel in my class had to be excused from doing it as she had a nut allergy.

 

If you take your driving test in a car that has a full manual valve body in its transmission, do you get an automatic's only licence because you aren't using a clutch or do you get a full licence because you still have to change gears?

I only remember the class clown asking what would happen if he burned a whole Marathon (school experiments in the days before Snickers!!!!).

And water can explode, providing you heat it past the point of boiling but not actually have it boil. For instance if you 'boiled' a glass of water in a microwave and then dropped something like a metal teaspoon or fork into it straight after...

I done my hgv test in something similar, a merc atego, and you only have to push the stick forward, or back and the computer selects what gear you need depending on speed, load and conditions, you just have to dip the clutch to change gear, but it was still classed as manual
