Answer 2

umm i dont know Sania,
:(( Sorry

Answer 3

oh! its ok

Answer 4

I don't know, but I would guess that they used water because it has a fairly low boiling temperature, it's cheap and common, and has a high heat capacity (meaning it can absorb a lot of heat before raising temperature).

Answer 5

I don't know what a heat pump is or does, so you'll have to explain it a little bit for me to make a better guess.

also, water doesn't combust, which might be good too. you don't want to be heating something and then have something just explode on you, like gasoline might lol.

this explains wht Is a heat pump

Answer 9

Oh, so basically this is just a thermodynamic system found in the back of every refrigerator today. When it says it transfers heat from a low temperature to a higher temperature, that's what's going on in your fridge right?

Water boils at a fairly easily at room temperature when the pressure is lowered and it is very cheap and common so that's probably why it was used. Also, in the past, production of these systems was probably not very secure, so you might have leaked out other gases easily and methods for obtaining other pure gases was probably harder and more expensive. That's a guess though, but it seems likely to me.

Answer 10

bt the q' is y is not in used anymore ?
