A material must gain energy both before and during melting.
No. They gain.
As the particles in solids are heated, they gain more kinetic energy, resulting in the particles vibrating more. This means that the bonds between the particles are broken, or weakened, meaning that the solid loses its shape and structure and melts in to a liquid.
A solid melts when it gains enough thermal energy.
A Physical change -to you unlucky study islander
Solid particles vibrate while locked in place. As they receive more energy, particles speed increases. Once the particles have enough energy they break apart and slide past each other as a liquid. The particles speed continues to increase as energy is added. Finally, they gain enough energy to break free and move independently as a gas.
No. They gain.
when u melt ice the hot particles transfer heat to the cold particles (ice) and the hot particles lose kinetic energy and the cold particles gain kinetic energy till the bonds relax and reaches the same temp

anytime a substance changes it's molecular structure (solid to liquid, liquid to solid, liquid to gas, solid to gas, gas to liquid) it loses engergy.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
particles of solid gain energy from the higher temperature outside and begin to move faster overcoming the forces of attraction between the particles and turn into a liquid!
