Question

Explain why pipes in colder countries often burst in winters with suitable explanation

Answer 1

heya!
here's your answer!

this explanation requires a bit of dive deep into the sea of physics , 

so the explanation goes like this : 
as we know , 
that when temperatures drop down - water changes into ice - temperature goes below 0° - i.e. the freezing point . and when this temperature decreases , keeping mass as a constant which it usually is ,

since temperature is directly proportional to volume when temperature is decreased , the volume decreases too ..

now , since when volume decreases , pressure increases .. because pressure is inversely proportional to volume .

hence , 
pressure increases - thus a greater force us exerted on the pipes which compels it to burst up.
