What is the increase of the volume of a substance by the increase of temperature called?
The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.
What is thermal expansion and explain its two types?
Thermal expansion is the tendency of a material to change in volume, length, or area in response to a change in temperature. The two main types of thermal expansion are linear expansion, where an object grows in length in one dimension, and volumetric expansion, where an object expands in all dimensions.
What is a good sentence for the word thermal expansion?
Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.
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
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.

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 jobs that require the use of thermal expansion and contraction?
Cement laying, for one job.
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.
What is the Coefficient of thermal expansion for oxygen?
The coefficient of thermal expansion for oxygen is approximately 0.0012 per degree Celsius. This means that for every one degree Celsius increase in temperature, oxygen will expand by 0.12% of its original volume.
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.
