Which scenario best matches the description below:

When a substance is heated, the particles gain energy and vibrate faster. As the temperature continues to rise, the bonds between the particles weaken, they expand and the substance changes state.

• Particles gaining heat

• Particles losing heat

Which scenario best matches the description below:

When a substance is cooled, the particles lose energy and vibrate slower. As the temperature continues to fall, the bonds between the particles strengthen, they contract and the substance changes state.
