Answer» Solid is the STATE in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its containerTheir vibration is related to their kinetic energy. In the solid the particles VIBRATE in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. ... Gas – In a gas, particles are in continual straight-line motionAs ice MELTS into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them TOGETHER as a solid, RESULTING in a change of state: solid -> liquidExplanation: |
