Maybe a silly question but; how can a water world have a temperature hotter than Venus, for example?

Interesting, what were the numbers? I did find this

Might also depend on the atmosphere, if there's a high atmospheric pressure, for example, water behaves differently than it does under Earth's one atmosphere pressure.
never heard that before maybe the water is boiling hot cant land so we will never know
It can, period.It can't, period.
But yes, a very very good question
And yes it was a good question.
As aRJay said - atmospheric pressure is an important factor - water in the same pot on the same gas burner is going to boil at a higher temperature at sea level than, for example, in the mountains at 2000 meters above sea level. Add to that changes that different compositions can make, as mentioned by Darrack - pure water and a soup made with the same water will boil differently - results of such combinations could be quite extreme.
reciept time kfc chicken salted water,so why did burn my bacon and that was salted lol.i dont think there is a straight answers to the oringinal post ,i cant think of one anyway,but fair question asked.
Higher pressure.
So... if water on the planet was held at ~100,000kPa, you'd get a boiling point of roughly 512 degrees celcius, which is a x1000 increase in pressure on compared to the surface of Earth.
The main source of that would be gravity.... theoretically, superheated water near the Earth's core could exist at pressures of around 31kPa giving a boiling point of around 397°C which gets close to 390°C, which is getting close to venus temperatures. So if you had a very high gravity water planet, you could definitely get there.
Boyle's Law.
I believe the James Web found a planet TOI-270 d with an estimated water temperature of 373K, Venus facing Sol is about 740K, im pretty sure stuff happens to pure water at around 600K so i am guessing (and i aint Brian Cox) the water would have to be more of a gaseous liquid to be close to the temperature of Venus.
We are discovering strange stuff in our own system every day so you never know.

You don't boil bacon, and keep an eye on it.
All the answers seem valid although I'm having difficult imagining Earth -sized worlds (and very many of these water worlds seem to be) having such excessive atmospheric pressures.
The amount of salt you add for cooking doesn't even add half a degree. To get to 104 degrees you need to add more salt than you find in seawater! But the salt does make the water come to the boil faster and it's easier to keeping it boiling because it changed the "specific heat" which is how much the temperature rises per amount of heat (energy) you pump into it.Salted water has 104C degrees to boil on Earth at the sea level. That's why we cook all salted
I did not know that! Nom nom.
For the same reason someone at work lost their bacon sandwich when they tried to heat it in the 1000°C lab furnace.
I've seen water worlds in the game with atmospheric pressures much higher than Earth.
Trying to remember what the body was that I noted in excess of a million atmospheres, I normally don't take much notice of standard bodies, so my have been water / ammonia / ELW,
In our galaxy, in RL, goodness knows, all we have is a game, after all.
