when a metal such as copper is heated it expands.explain what happens to the metal particles as the solid metal expands?
Answers
Explanation:
When a metal is heated the kinetic energy in the particles increases and hence the force pf attraction decreases among the particle (as electrons try to escape due to kinetic energy). This causes the metal to expand..
When a material is heated, the kinetic energy of that material increases and its atoms and molecules move about more. This means that each atom will take up more space due to its movement so the material will expand. ... Some metals expand more than others due to differences in the forces between the atoms / molecules.
Answer:
when a solid is heated gradually it starts expanding it means that the bond of particles of the solid is weakening a stage comes when the solid start to transform into liquid by continously heating it and the bond of atom of the element or metal breaks completely at this stage.
