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.
Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
A mole of any substance contains Avogadro's number of particles (6.02 x 10^23). The molar mass of copper is less than that of lead, so a mole of copper atoms weighs less than a mole of lead atoms, despite both containing the same number of atoms.
Why aluminum reacts so slowly with copper sulphate?
Aluminum reacts slowly with copper sulfate because aluminum is more reactive than copper. When aluminum reacts with copper sulfate, it forms aluminum sulfate and copper. This reaction can be slow because a layer of aluminum oxide may form on the surface of the aluminum, inhibiting further reaction.
Which element has a larger atomic radius than aluminum AL?
Sodium (Na) has a larger atomic radius than aluminum (Al).
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.

Compare conductivity of iron copper and aluminum in terms of electricity.?
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
What are the differences between aluminum and copper in terms of conductivity and cost?
Aluminum has lower conductivity than copper, meaning it is not as efficient at conducting electricity. However, aluminum is cheaper than copper, making it a more cost-effective option for certain applications.
