The expansion rate of iron varies depending on the specific type of iron and the temperature. In general, iron expands when heated and contracts when cooled, following the principles of thermal expansion. The coefficient of thermal expansion for iron is around 11 x 10^-6 per degree Celsius.
What else can I help you with?
When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?
The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion
What happens to the bimetallic strip when the iron is hot?
When the iron is hot, the bimetallic strip will bend towards the iron due to differential expansion of the two metals in the strip. This bending occurs because the metal with higher thermal expansion coefficient will expand more, causing the strip to curve towards that side.
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.
How fast is the expansion of the edge of the universe occurring?
The expansion of the edge of the universe is happening at a rate of about 46 miles per second per megaparsec.
What is the rate of expansion of the universe in terms of the Hubble constant, which is approximately 70 km per second per megaparsec?
The rate of expansion of the universe is measured by the Hubble constant, which is around 70 kilometers per second per megaparsec.
When treating iron becomes frosted then it is?
The expansion rate of liquid nitrogen is?
Order of expansion rate aluminium copper brass and iron?
Linear thermal expansion (α): Iron - 11,8.10-6/°C Aluminium - 23,1.10-6/°C Copper - 17.10-6/°C Brass - 19.10-6/°C See the link below for a more complete table.

What is a good data transfer rate for a PCI expansion card?
A good data transfer rate for a PCI expansion card is between 200 and 400mbps.
When is expansion a good thing?
Expansion at a relatively slow rate is more desirable than an explosion.
What is the expansion rate of nitrogen liquid to gas?
The expansion rate of liquid nitrogen is 697 to 1.
Does all liquid has the same rate of expansion and contraction?
No, they vary

What was the death rate on the Oregon Trail during the westward expansion of the United States?
During the westward expansion of the United States, the death rate on the Oregon Trail was estimated to be around 10.
What increases the rate at which iron rust?
Exposure to water and oxygen accelerates the rate of iron rusting. Additionally, high levels of acidity in the environment, as well as the presence of salts or pollutants, can also increase the rate of iron corrosion.
