What else can I help you with?
Aluminum has a specific heat capacity more than twice that of copper Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be?
The copper wire will undergo the fastest increase in temperature because it has a lower specific heat capacity compared to aluminum. This means copper can absorb heat more quickly and reach a higher temperature faster than aluminum when exposed to the same amount of heat.
What happens if you put copper metal into a solution of aluminum sulfate?
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
How are a copper wire and aluminum foil alike?
negative charges can't move through them
Why does more current flow through the bulb when the reed switch was replaced with copper wire?
When the reed switch is replaced with copper wire, the circuit becomes a closed loop with significantly less resistance compared to the reed switch. This lower resistance allows more current to flow through the circuit, including the bulb. The increased current flow results in the bulb glowing brighter as it receives more electrical energy.
Why does copper ii sulfate react with aluminum?
Yes. Iron is more reactive than copper, so will displace it from a compound. If you put a piece of iron into copper sulfate solution, it will be soon coated with a deposit of orangey red copper.CuSO4 + Fe --> FeSO4 + Cu
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
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.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.
Does copper have a higher resistance to electron flow than aluminum?
Tungsten has high resistance, here is an example, in incandescent light bulb,there is a filament made up of tungsten (metal),when we turn on the switch the electricity flows through the filament making it heat up, NOW what heats up the filament is TUNGSTEN's resistance, HOW AND WHY: 1)Tungten has a high resistance, which mean that more electrons accumulate, as more electrons accumulate it heats up the filament due to resistance, it's just like : when you are cold you rub your hand together to make them warm there is a force called friction that heats up your hands due to the contant rubbing, same is here, when electrons accumulate, they become more resistant, i.e unable to move quickly, so when they can't move easily they began interacting and producing heat, the tungsten metal that is known to have high resistance helps it heat up and light up up as well, if tungsten was not resistant it would melt up at high temperature.
Why is rotor in energy meter made of aluminum why not copper?
Aluminum is much lighter than copper and has a lower conductivity which makes it easier for it to create more force. It is also much cheaper than copper.
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.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
What is the weight of aluminum conductor as compared to a copper conductor?
Aluminium weighs less than copper for the given volume
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.
Aluminum has a specific heat capacity more than twice that of copper Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be?
The copper wire will undergo the fastest increase in temperature because it has a lower specific heat capacity compared to aluminum. This means copper can absorb heat more quickly and reach a higher temperature faster than aluminum when exposed to the same amount of heat.
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.
