The reason there are cracks in sidewalks instead of just one continuous piece of concrete is to provide for thermal expansion. Without the expansion cracks, as the concrete heats up it expands it would have no where to go so the sidewalk would buckle. Also, in the winter when it gets cold the concrete would shrink and crack/break.

How would you use Thermal expansion in a sentence?
Example sentence - Our homework assignment is to give an example of thermal expansion and explain why it happens.
Solid metals undergo greater thermal expansion than liquids do?
false
What happens to the particles in a solid when it is heated but not melted or burned?
Thermal expansion occured.
What is thermal expansion and contraction of matter?
Thermal expansion will occur in just about all of the 15 or more phases of matter: whether it be solid, liquid, gas, etc.
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion

Does a solid have fixed volume?
Ignoring thermal expansion - yes.
Solid metals undergo greater thermal expansion than liquids do?
false
What happens to the particles in a solid when it is heated but not melted or burned?
Thermal expansion occured.
What is the scientific name for the inrease in the size of a substance when the temperature is increased?
Thermal Expansion. Each liquid or pure solid has a specific thermal of expansion. The thermal expansion of a substance is not linear, though for most of the temperatures we encounter in normal life, it is close enough to linear to be able to use a linear definition called the "Coefficient of Thermal Expansion".
What are example of thermal expansion?
a Mercury thermometera mechanical thermostat
What is thermal expansion and contraction of matter?
Thermal expansion will occur in just about all of the 15 or more phases of matter: whether it be solid, liquid, gas, etc.
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 is liquid rising in a thermometer as temperature increases is an example of?
Thermal expansion.
What is the increase of the volume of a substance by the increase of temperature called?

What is a jar with its lid on tightly an example of?
Thermal expansion and contraction, specifically the different coefficients of thermal expansion (CTE) between glass and metal....AND ITS LIKE A (CLOSED SYSTEM)
The thermal expansion of a solid is caused by?
