- "Concrete roads and sidewalks are built in sections, with space left between the panels. Otherwise, they would crack on very cold days and heave and buckle on very hot days.
- The traditional way to fasten an iron rim to a wooden wheel (or put an iron hoop around a wooden barrel) was to heat the rim red hot. This made it slightly larger, so that the wheel could be forced into the rim; after the rim cooled and shrank, it was firmly held in place. The modern version of this is that one should not mix bolts and nuts made of different metals -- there will be a temperature range in which the bolt is larger than the nut (and the nut is then frozen in place), and another range where the nut is bigger than the bolt (and then it is not held in place securely).
- A modern application of thermal expansion is in the design of the power plants for nuclear submarines. Instead of trying to control the power level by pushing in and pulling out control rods, the reactor is designed so that when it is too hot it expands (which decreases the rate of reaction), and and when it is cool is contracts (which increases the rate of power production). Thermal expansion eliminates the need for an operator that never gets distracted or a complicated electrical circuit.
- If the ocean becomes 1 degree (oF) warmer, its volume will increase by 0.01%. Since the ocean is several miles deep, this implies that the surface will rise about a foot, giving a change in the sea level. In the process, the beach line moves landwards 20 feet. People owning beach houses (or even living close to the ocean) find this alarming."
What else can I help you with?
What are not an example of thermal expansion?
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
What are two examples of thermal expansion in solid?
Two examples of thermal expansion in solids are the expansion of a metal rod when heated, causing it to increase in length, and the expansion of a bridge beam on a hot day, resulting in the beam bending slightly due to the increase in temperature.
What are some non examples of thermal expansion?
Some non-examples of thermal expansion would include the boiling of water, which involves a phase change rather than expansion due to temperature increase, and the stretching of a rubber band, which is a different mechanism of deformation unrelated to temperature change. Additionally, the growth of a plant is not an example of thermal expansion.
What are examples of thermal expansion of a liquid?
Examples of thermal expansion of a liquid include water expanding as it is heated, causing liquids like mercury in a thermometer to rise when exposed to heat, and gasoline expanding in a fuel tank on a hot day.
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.

Two examples of thermal expansion?
Just about any material will expand if heated.

a Mercury thermometera mechanical thermostat
Examples of thermal expansion in solids through heat?
Not sure what you mean; basically, ANY solid will expand if you heat it.
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.
The change in an objects volume that occurs when heat is added is called?
thermal expansion
Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
How does thermal expansion affect a bridge?
A bridge must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion
The expansion of matter when it is heated is known as?
thermal expansion
