The most accurate response regarding the changes that will occur on a microscopic level as gallium melts in someone's hand is:
The gallium atoms will gain kinetic energy.
This is because melting is a phase change where the solid gallium absorbs heat, causing the atoms to vibrate more vigorously and gain kinetic energy, which leads to the transition from solid to liquid.
