Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options. However, when a solid substance is subjected to heat, it's particles will have an increase in kinetic energy which causes the solid to fluidize as it changes state to liquid (or fluid). The same thing can be said about the heating of a silver strip, the silver particles will have an increase in kinetic energy.
It should be noted that the particles of a solid substance generally have very little or no kinetic energy, thus the reason for the compact shape of a solid.
