Closed-loop piping systems are used extensively to circulate heated or cooled water (or other liquid) to provide heating and cooling for buildings. The problem is that the liquid filling the pipe is not compressable. When the temperature increases, the liquid expands, and can burst pipes and coils, wreck pump seals, and generally wreak havoc. The solution is to plumb a tank filled with air into the system. Sometimes there is a rubber bladder separating the water from the air, sometimes not. Either way, when the water expands, it flows into the tank, compressing the air instead of wrecking something. It gets it's name from the fact that the expansion of the liquid is caused by heat, thus thermalexpansion tank.
What else can I help you with?
What is the shrinking of a substance called?
Since expansion is the process of a substance's dimensions increasing, e.g., thermal expansion caused by a rise in temperature, the logical opposite would be contraction.
What is liquid rising in a thermometer as temperature increases is an example of?
This is an example of thermal expansion, where the liquid in the thermometer expands as it is heated, causing it to rise within the tube.
What kind of weathering causes repeated expanding due to the heat and contracting due to cold strains the rocks and causes them to crack?
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
What term is given to the non expansion of material at high temperatures?
The term is "thermal expansion." When materials are heated, they typically expand due to increased molecular motion. Not expanding at high temperatures would suggest that the material has a low coefficient of thermal expansion.
When the temperature of a body is increased the stress induced will be?
When the temperature of a body increases, the stress induced is typically thermal stress, which arises due to the expansion of materials. If the body is constrained and unable to expand freely, this thermal expansion leads to compressive or tensile stresses. The magnitude of the induced stress depends on the material's coefficient of thermal expansion and the temperature change. If the body can expand freely, no thermal stress will develop.
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.
When an object is heated it increases What is this called?
When an object is heated, it increases in temperature. The process of an object gaining heat and becoming warmer is known as thermal expansion.
How is hydrolysis similar to thermal expansion?
Both hydrolysis and thermal expansion involve a change in the structure of a substance. While hydrolysis is a chemical reaction that involves the breaking of bonds by adding water, thermal expansion is a physical process where materials expand or contract in response to changes in temperature.
When a substance is heated what is it called?
Thermal Decomposition
What is the process by which the liquid in a thermometer or sections of a sidewalk increase in volume at a higher temperature?
thermal expansion
Describe A process that converts chemical energy to thermal energy?
Burning a material converts chemical energy into thermal energy.
What is the process called when heat causes metal to expand?
The process is called thermal expansion. When metal is heated, the increase in temperature causes its particles to vibrate more vigorously, leading to an expansion in size.
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 the force behind weathering by thermal expansion and contraction?
The force behind weathering by thermal expansion and contraction is the repeated heating and cooling of rocks, causing them to expand and contract. This leads to the breaking down of rocks into smaller pieces due to the stress created by the expansion and contraction process.
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
