The coefficient of linear expansion for copper is around 16.5 x 10^-6 per degree Celsius. This means that for every degree Celsius increase in temperature, a one-meter length of copper pipe will expand by 16.5 micrometers in length.

What is the relation between the coefficient of linear and superficial and volume expansion respectively?

The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.


A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?

The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.


Why liquids have two coefficient of expansion?

Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.


When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?

The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion

Why aluminum has high thermal expansion coefficient than Copper?

Aluminum has a higher thermal expansion coefficient than copper because its crystal structure allows for larger atomic movements when heated. This results in a greater expansion of aluminum compared to copper when exposed to heat. Additionally, aluminum has a lower density and stronger interatomic bonds, leading to a higher degree of expansion when heated.


A copper water pipe is 10.000 meters long when installed in a building on a day when the temperature is 9.0 degrees C. How much does the pipe expand when it carries hot water at 87 degrees C?

The coefficient of linear expansion for copper is 17 x 10^-6 per degree Celsius. Given the temperature change from 9.0 to 87 degrees C, the temperature change is 78 degrees C. Thus, the expansion of the copper pipe would be 10.000 * 17 x 10^-6 * 78 = 0.01326 meters or 13.26 mm.

What is the cubical coefficient of thermal expansion for metals?

Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
