What happens to metals when heated?
Understand the Problem
The question is asking about the physical and chemical changes that metals undergo when they are subjected to heat. This includes changes in their properties, appearance, and structure.
Answer
Thermal expansion due to increased kinetic energy.
When metals are heated, the particles gain kinetic energy, causing them to move more randomly and leading to thermal expansion.
Answer for screen readers
When metals are heated, the particles gain kinetic energy, causing them to move more randomly and leading to thermal expansion.
More Information
Thermal expansion is a common property of metals due to the increase in particle kinetic energy. This process can also affect other properties, such as electrical resistance and magnetism.
Tips
A common mistake is to overlook that different metals may expand at different rates due to varying coefficients of thermal expansion.
