Question

Give reason why copper is used to make hot water tanks and not steel( an alloy of iron)?

Answer 1

hey frnd....
Copper is used to make hot water tanks because it doesn't react with hot water and it doesn't get rust.
while steel which contains iron reacts with hot water to form rust which is not good at all.

HOPE THIS HELP YOU ☺☺❤❤❣❣

Answer 2

copper is only a metal which is a good conductor of heat so it heats the water fast

while steel which is an alloy of iron is a mixture of other metals with different properties

hence copper is better to make hot water tanks and not steel
