it makes noise because its trying to expand which don't make sence i know but if u take a straitner and you turn it up as hot as u can which on mine is 360 and u turn it off then put it under the sink it will make a craking noise and it will try to cool the straitner but it can burn u still if the water isn't cold enough i have done it and the hospital already nows me hahahahahahaha poor hospital but if u do that then it will crakle but don't do it if u don't want to get burned because u will get burnded no matter wat u do
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
It is dew or ozone
no ,Because when the temperature increases the metal expands and when the temperature is low the metal contracts
Metal expands from heat and contracts in cold
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.
Bizmuth is a heavy metal that expands on cooling and contracts on heating. it is used for making lead free ammunition, especially for shotgun rounds and airgun pellets as it is considered non-toxic. It is also used in the glass making industry for making 'float' glass sheets.
all material expands and contracts when the temperature goes above or below the COE (coefficient of expansion) of said material.
Metal expands in the heat and contracts in the cold, so the noise you are hearing is the metal growing/shrinking due to the changes in temperature.
This website shows how to make a barometer http://www.all-science-fair-projects.com/science_fair_projects/21/293/d7c135af11e2b5d5795246439f794952.html
Your answer is in the question. If something expands, it obviously gets bigger. Therefore, the metal will get larger.
Almost all of them, but bridges can be a very good example. The small rubber tracts are for when the bridge expands and contracts. Metals also do a good job. There is a way to make a quazi thermometer that uses the expansion and contraction of metal wire to pull a pin.
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
