must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion

How would changes in temperature would affect a bridge?
Thermal expansion means that the length of the bridge changes.
How does Thermal expansion and contraction affect dental waxes?
it expands and ur bf
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
Why are some bridges supported by rolles at one side?
Thermal expansion and contraction can put huge stresses into a large structure such as a bridge. To minimise this effect, the rollers are designed to allow the end of the bridge to move with the expansion and contraction.
What is an expansion bridge?
bridge expansion is when one side of the bridge needs to be propped up
What is thermal expansion and explain its two types?
- Thermal expansion is the dimension modification of a material under heating. - Linear, volumetric and area thermal expansion are known and measured for materials.
Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
The expansion of matter when it is heated is known as?
thermal expansion
What is the process of thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
What are the two types of thermal expansion?
Linear, volumetric and area thermal expansion are known and measured for materials.
What is the thermal expansion coefficient for steel c 15?
thermal expansion depends on Temperature and material of steel
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.
