In that, apparently you can bet with odds of 1000/1 on a certain character being on the throne at the end, or 4/1 on another.

But since the TV show has already been filmed and produced, many must already know the outcome of the show, how is that something that can be bet upon where those in the know would be able to do so? Do they just have to be trusted not to, or do the bookmakers do extensive background checks on who is claiming the win?
I get where are you are coming from. You can bet on anything so long as the outcome isn't known, but in this case the outcome is known.

Having said that, I believe that several endings have been filmed and even the cast don't know which one is going to be used. So the outcome is probably a closely-guarded secret.
Its a secret, but it is known, was my point.

but the point above is maybe more relevant, that they are using it to generate the traffic to the site for the small number of people who will sign up and have a punt, that's another email address or app download they can use I suppose!

As long as they can set prices to make sure they take more from the losers than they give to the winners, I doubt they really mind. They're still ahead.

The alternative is taking no bets on that market at all, and there's no living to be made there.

Don't bookies set the odds dynamically based on the bets that are being laid anyway? ie whatever the outcome the bookies should still make a profit.

yes Bookie (as opposed to exchange) odds have more to do with how the public is betting than the statistical likelihood of an event.

If you keep a pan of water on the stove until it boils, then leave it boiling, does the water temperature climb above boiling point or does it stay at 100C ?

It stays at 100C (assuming that's the boiling point at the time). The extra energy you pour into it is used turning the liquid to a gas.

There are tricks you can do to superheat water, but exposed to the atmosphere in a pot the liquid can't exceed its boiling point.

Related question- can you boil/melt carbon into a gas/liquid?

its all depends on atmospheric conditions, you can melt carbon and also make it sublime, dependable of atmos pressure,

Put the lid on it and it will get a little higher. Weld the lid on and it will get a lot higher. That is, until it explodes and showers your kitchen in scalding hot superheated steam.

Apparently you can't make a decent cup of tea on top of high mountains because the low pressure gives a boiling point well below 100 so you can't get the water hot enough.

True, since the boiling point of water varies by pressure.

If you had some kind of pressurised kettle then you could get the water hot enough, but not with atmospheric pressure at that altitude.

Using that to our advantage, one way of producing large quantities of drinking water from sea water is by lowering the pressure to allow it to boil off at a much lower temperature. This saves a lot of energy as you are only heating to around 78degC rather than 100. The fact that you can also use the cooling water from a ship's engine(s) to attain that lower temperature mean you are essentially making drinking water 'for free'.

This is how your car engine survives btw, the water system is sealed with a typical blow off pressure of 1 to 1.5 bar. Because of that the water can go beyond 100°c without boiling.

...and because coolant doesn’t boil at 100 degrees anyway.

Why do we have an "&" symbol for "and" but not one for the common "the".
I suspect it's because '&' is a stylised plus, just like '@' is a stylalised 'a' with a tail that evokes the 't', but there is no equivalent for 'the' that lends itself.

One abbreviation I picked up at school in science classes was a lower case 'w' with a bar over it for 'with'. And three dots in a triangle for 'therefore'.

Also, now that I think of it, the easiest way to shorten 'the' is to omit it altogether.
Sithee, folks in Yorkshire ahead of you there.

You can heat water above 100DEG even under normal pressure, so long as it doesn't boil. You need some kind of disturbance in the water to trigger boiling, such as that caused by uneven heating, which is why water almost always boils as soon as it's hot enough. But in certain circumstances such as gradual heating in a microwave this might not occur. Until you disturb it, then it boils over spectacularly and potentially dangerously.

Are you saying that water doesn’t turn to steam at 100c unless it’s disturbed?

Yes, but it’s hard to create the circumstances at home.

You need a nucleation site to start water boiling, if you heat it evenly in a smooth container (an unscratched glass for instance) you can raise the temperature over the normal boiling point. If you disturb it and this provide a nucleation site it will boil explosively until the temperature reduces to the boiling point.

In the glass in a microwave scenario this normally means a steam explosion throwing scalding water around.

You can also supercool water in plastic bottles so it is liquid at below 0C, when you tap the bottle it will rapidly turn into ice.

I heated a cup of water in a motorhome microwave once (the low wattage kettle just took too long).
I thought it must be hot enough now but when I took it out it wasn't bubbling. When I put the teabag in and pushed it into the water it reacted like a geyser!
