The process is called thermal expansion. When the metal lid is heated under hot water, its particles gain kinetic energy and move more freely, causing the lid to expand in size.

What is the process called when particles in a metal lid expand under hot water?

This is a misconception. Particles do not expand, When they get hot they move further apart. This means that the object (the lid) gets bigger. It's just called expansion.


What is the process called when heat causes metal to expand?

The process is called thermal expansion. When metal is heated, the increase in temperature causes its particles to vibrate more vigorously, leading to an expansion in size.


What is a piece of metal in a bridge that allows it to expand and contract?

A expansion joint is a piece of metal in a bridge that allows it to expand and contract with changing temperatures without causing damage to the structure. This helps prevent the bridge from cracking or collapsing under temperature variations.


How can a metal bar be made to expand in all directions?

Heating the metal bar evenly will cause it to expand in all directions. This is known as isotropic expansion, where the material expands uniformly in all dimensions. Heating allows the atoms in the metal to move more freely, causing the entire metal bar to expand uniformly.


When was the process of metal injection developed?

The process of Metal Injection was developed in the early 1970's by Raymond Weich. It allows for metal particles to be injected in plastic machining parts.


What is the reaction of metal with oxygen called?

The reaction of a metal with oxygen is called oxidation. This process can lead to the formation of metal oxides.


What is the process called when you combine metal and oxygen?

The process is called oxidation, where the metal combines with oxygen to form metal oxides. This can result in the formation of rust on iron or tarnish on silver.


Will a metal expand if it's thicker?

Yes, metal will expand when heated regardless of its thickness. Thicker pieces of metal will expand in all dimensions, but the expansion will be proportional to the increase in thickness.


Why gaps left between two sections of rail tracks?

Metal can expand slightly when heated by the sun, a small gap allows the rail to expand, that said modern rail tracks are welded and do not have these gaps.


What is the process called for the combining of metal with oxygen?

Rusting


The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called?

The process of transferring the cost of metal ores and other minerals removed from the earth to an expense account is called depletion. This accounting method allows companies to allocate the cost of natural resources over time as they are extracted and sold.


What is the process of obtaining pure metal from ore called?
