Copper pipes are typically made of pure copper or a copper alloy, such as copper mixed with small amounts of other elements like zinc or tin. The composition may vary depending on the specific requirements of the application, but copper pipes are known for their durability, malleability, and resistance to corrosion.
The specific heat of copper at standard temperature and pressure (STP) is approximately 0.385 J/g°C. This means that it requires 0.385 joules of energy to raise the temperature of 1 gram of copper by 1 degree Celsius at STP.
