ProfessorBrass is an alloy of copper and zinc, known for its golden color and resistance to corrosion. Iron is a pure metal with a silvery-gray color that is prone to rusting when exposed to moisture. Iron is much stronger and more durable than brass, but brass is more resistant to corrosion.

Would brass or iron expand in a bimetallic strip?
Brass and iron have different coefficients of thermal expansion, so when exposed to a change in temperature, they would expand by different amounts. This difference in expansion causes the bimetallic strip to bend due to the unequal expansion of the two metals.
Is brass attracted to magnets?
Yes, brass is not attracted to magnets because it does not contain any magnetic properties like iron or steel. Brass is an alloy of copper and zinc and does not have ferromagnetic properties.
What way does a bimetallic strip bend with iron and brass?
When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
What are the 2 main differences between plastic things and iron?
One main difference is that plastic is a synthetic material made from polymers, while iron is a naturally occurring metal. Another main difference is that plastic is typically lighter and more flexible, whereas iron is heavier and more rigid.
Iron has linear expansivity of 0.000012k brass has a linear expansivity of 0.000019k . draw diagrams to show what will happen to a bimetal strip made from ironand brass if it is heated or cooled.?
When the bimetal strip is heated, the brass side will expand more than the iron side due to its higher expansivity, causing the strip to bend towards the brass side. When cooled, the brass side will contract more than the iron side, causing the strip to bend towards the iron side. This bending can be used in devices like thermostats to control temperature.
