generally on heating metal _______​

Answer 1

Answer:It expands

Explanation:

hello man

generally on heating metals it expands, or melts(if it is heated to a very high temperature). This is why blacksmiths usually heat metals and make tools out of them

Answer 2

Answer:

Generally, on heating metal, the metal expands.

Explanation:

• The metal expands when heated and compresses when cooled. Any metal can alter with this technique.
• A bullock cart's wheel is fitted with metal rims using this theory.
• The wheel is constructed somewhat larger than the rim.
• Then, using heat, this metallic rim expands and easily fits around the wooden wheel.
• The metal contracts as it cools, snugly fitting into the wooden wheel as a result.

So, generally on heating metal, the metal expands.
