ok, im a bit too lazy to do some researching for this...so i thought i was ask here. i was never really good with hard sciences, but can you check if this is true? i have to do a presentation with boiling water in a vacuum chamber tomorrow. h:

when heat is applied to solid water, it melts and turns into liquid water. if heat is applied to liquid water, it turns into water vapor (evaporate). if enough heat is applied to liquid water, so that the pressure of the vapors is the same as the air pressure around the water, it is called boiling.


h: if there is an easier way to explain this...holla.

 

yeah
it's true.

which is why water boils at below 100C when you're like 10000 feet above sea level

 

sweet. can you explain why there are "bubbles" h:

in the vacuum chamber, the water boils at room temp... im learning while im teaching. h:

 

raw eggs are cooked in 10 minutes

 

thats debatable. h:

 

easier way to explain this? yeah...



heat melts ice into water, more heat turns water into gas :exnbp:

 

i don't remember why there are bubbles. I've been out of school too long.

remember you just have to be one lesson ahead :chuckles:

 

but that doesnt plain boiling. h:

 

thats the rule i live by h:
