If 18cm3 of water weighs the same as 24L of steam, what does that tell you about the number of particles in 18cm3 of water and 24 litres of steam

 

[breezer]

more or less

 

[Shutpa]

more or less

Come on Breezer, you can do better than that. It's needed for tomorrow!

1m3 of water = 1000 litres; you can do the math from that to get how many litres 18cm3 is, surely?

Maths doesn't come into it, I'm told.

If it weighs the same, then the number of particles are the same, so what was the question again? OK it goes to show that steam is a lot more spread out than water.

thats either a trick question or a badly phrased one. the number of particles is equal in the water and the steam.

 

[Shytalkz]

Still tells you something about the relative densities, though

 

[peteftw]

then it if you divide them both by 6 you get realitive densities of 3/4

If 18cm3 of water weighs the same as 24L of steam, what does that tell you about the number of particles in 18cm3 of water and 24 litres of steam

It only tells me that the 18cm3 of water has the same mass as the 24L of steam and therefore the same number of particles.

 

[^woody^]

It tells me that the number of particles remain the same, but they are spread out (less dense) when heated to 100 degree c at normal atmospheric pressure

Presumably the 24l of steam could be pressurised to make it occupy 18cm3

 

[noseall]

what happens when you superheat the steam eh?

now then, now then.

what happens when you superheat the steam eh?

now then, now then.

more or less the point, weight will remain the same, clearly, the density will alter according to the pressure of the steam.

what was the point of the question anyway?

actually there never was a point to the question, no question was actually posed.

strange the ways some peoples minds work
