Help for a beginner please

[just learning]

Hi, i am a couple of weeks into a college course and have a question i would be grateful for some help with. Can anyone tell me "What problems might the changing density of water in relation to temperature cause plumbers"? Many thanks in advance.

 

[Plouasne]

Water changes density when it turns into ICE, ice also expands and if a plug of ice forms in a pipe and does not move, because of , say an elbow, as the ice expands, it exerts a compressive force on the water, water can not be compressed, so this force could cause a compression fitting to "blow off", the pipe or the pipe can burst

Many thanks, had found something similar in meaning somewhere but they didn't quite word it so i could picture it. You, on the other hand have done just that. Thanks again for your help.

Heres one for you
at what temperature is water at its greatest density ?

 

[helpsy]

4 degrees c

What scale is absolute temperature measured in?

 

[traineedrip]

Kelvin

who's kelvin?, is he a member?.

 

[helpsy]

What are the lower/upper limits?

 

[Plouasne]

who's kelvin?, is he a member?.

If he is he's, a ghostly one

i dont know about you plouasne, well i think i do in this tense, but you learn all this stuff, even french for me (which i was very good at) and if you dont use it for years it goes somewhere in the cobwebs of my brain.
always had this brain concept of ''do i need to know that?'' then dont use up valuable storage space.
my wife says if i contract altsimers in the next ten years i have to let her know?.

p.s just kidding on thekelvin scale one though.
