When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?
Because copper has a higher thermal expansion coefficient than iron, when the bar is heated, the copper side expands more than the iron side. This causes the bar to bend towards the iron strip due to the unequal expansion of the two metals.
When a bimetallic bar made of copper and iron is heated bar bends toward iron?
This is because copper expands more than iron when heated, causing the side with copper to elongate and bend towards the iron side. This phenomenon is known as thermal expansion and is utilized in devices like thermostats to control temperature.
