Why does metal make noise when it expands or contracts for example hot-water pipes or an iron?
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

What state of matter expands with cold and contracts with heat?
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
Is Eiffel Tower always the same height?
no ,Because when the temperature increases the metal expands and when the temperature is low the metal contracts
Which metal expands on cooling and contracts on heating?
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.
What is a liquid metal that expands and contracts as the temperature changes and is the metal used in thermometers called?
The liquid metal used in thermometers that expands and contracts as temperature changes is mercury. Mercury is commonly used due to its unique properties, such as its wide liquid temperature range and high thermal conductivity, making it ideal for accurate temperature measurement.
Do metal exterior doors expand?
all material expands and contracts when the temperature goes above or below the COE (coefficient of expansion) of said material.
Why a metal ball contracts when a ring holds it after using a Bunsen burner to heat it?
The metal ball contracts when placed in a cooler environment because of thermal contraction. When heated with a Bunsen burner, the metal expands due to increased kinetic energy of its particles. Once removed from heat and placed in the cooler ring, the metal loses kinetic energy, leading to contraction.
Why does roofing sheet make racking noise during sunny periods and cold periods?
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.
How do you make a barometers?
This website shows how to make a barometer http://www.all-science-fair-projects.com/science_fair_projects/21/293/d7c135af11e2b5d5795246439f794952.html
How does a thermometer work?
A thermometer works by measuring the temperature of an object or environment using a liquid or metal that expands or contracts with changes in temperature. This causes the level of the liquid or the length of the metal to change, which is then converted into a temperature reading on a scale.
How does the rotary thermometer work?
A rotary thermometer works by using a metal coil that expands and contracts with temperature changes. As the coil expands or contracts, it rotates a pointer on a scale or dial to indicate the temperature. This movement is due to the principle of thermal expansion, where materials expand or contract when heated or cooled.
Why do train tracks expand?
Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
What are everyday examples of solids expanding or contracting due to temperature changes?
One common example is metal expands when heated, which can be seen in a metal bridge expanding on hot days. On the other hand, rubber contracts in cold weather, as seen when car tires lose pressure in winter. Another example is wooden doors expanding or contracting with changes in humidity levels, leading to difficulty in opening and closing them.
