~manting, vishan]]> 2021-03-08 01:14:47 UTC https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279812756 Since all the pipes in your home are full of water at any given time, thermal expansion creates pressure and stress that can cause damage or wear and tear. It all starts with your water heater. When water enters your home through the water main, some of it is directed into your water heater tank. https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279813070 Velkan and pohseng]]> 2021-03-08 01:14:55 UTC https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279813070 Lyra , Darwisya https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279813178 Telephone wire and electricity cables raised on poles contract in cold weathers .

Water pipes burst because the water inside them expands is it gets close to freezing, and this causes an increase in pressure inside the pipe. When the pressure gets too high for the pipe to contain, it ruptures. Jonathan and kaisshenglee

Rail expansion occurs when the temperature rises in summer, and the joints with proper length will be extruded and bulged due to rail expansion. If it is not serious, it will produce a bump, which will cause the train to run unsmoothly and send out an abnormal sound.The railroad track has vbeen a main cause for limiting the operating speeds of ... the railends, to allow for longitudinal thermal expansion of the rails on hot days. ... to determine the factors which have appreciable effects on the resistance of the  ...

So to overcome this problem, laboratory glassware have manufactured the inner glass and the outer glass of the laboratory glassware with different thickness.The inner glass would be thicker and the outer glass would be thinner.This is manufactured this way so that outer layer glass would expand first and prevent cracking]]> 2021-03-08 01:16:43 UTC https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279817296 https://padlet.com/hqlwa89/hkyg17jdejictmtr/wish/1279819641 Camouflaging in the dark

Hence, most of the glassware found in the homes and in laboratory are made of a special type of glass. Unlike ordinary glass, glassware is less likely to crack when hot liquids are poured into it. this is because the glass expands very little when heated.

Keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
