What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
What is a good sentence for the word thermal expansion?
it was a hot night and a thermal one too
One common application of thermal expansion is?
Thermal expansion has been used to create many different devices including the fire sprinkler. Fire sprinklers have a bimetallic strip which will bend to one side when heated to connect to electricity and trigger the sprinkler.Ê
Would a bimetallic strip work if the two different metals happened to have the same rates of expansion?
The one with the higher coefficient of thermal expansion.
Why is thermal expansion not visible in solids?
Thermal expansion in solids is normally very small - typically around one part in one hundred thousand for a one Kelvin temperature change. That means that a one metre long length of aluminium, for example, will only change size by 0.23mm when heated by 10kelvin - effectively invisible to the human eye. Thermal expansion, though can be visible to the unaided eye if the object is large enough - a kilometer long bridge, for example, may vary in length by as much as a metre or more between summer and winter, depending upon the seasonal temperature change, and will have expansion joints that allow sections of the bridge to expand into one another without changing the overall length of the bridge, and risking damage to the structure. If you were to look at these joints in winter and then in summer, you would see the difference that thermal expansion makes.

This increase of volume is called expansion
Where can one learn more about thermal expansion coefficient?
Thermal expansion coefficient is how matter reacts to temperature, one of the best places to find information for free is at your local library in the encyclopedia or online in a few places, Wikipedia is often a good source for research, there are also various engineering sites that will show up from searching the words "thermal expansion coefficient" that will give the information,

What is one common application of thermal expansion?
A thermostat is a common application of a thermal expansion. It works as an indicator with an internal liquid that rises up if the temperature in the room also heats up.
One common result of thermal expansion is?
volume increases ,pressure increases
What are the of objectives of thermal expansion in solids and liquids in everyday life?
one example of thermal expansion is when in the kitchen and you can not open a can of vegetable(example) you will put it in a pan of hot water and the water will push it off.
What are jobs that require the use of thermal expansion and contraction?
Cement laying, for one job.
Would a bimetallic strip work if the two different metals happened to have the same rates of expansion?
The one with the higher coefficient of thermal expansion.
What is the function of expansion valve?
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
How does solids liquids and gases react to temperature?
Magnitude in thermal expansion is how much the substance can expand, so, the relative order of magnitude of thermal expansion is: solid<liquid<gases. Gases expand more than liquid, and liquid more than solid.
What is better the one having less or more Thermal Expansion Coefficient?
Depends on your application. The Thermal Expansion Coefficient is a number which represents how much a material will physically expand with an increase in temperature. If you want it to grow as it heats, it is the better material.
