Describe what happens to the particles of a solid, in terms of movement and kinetic energy, as it is heated to its melting point, including whether this is a physical or chemical change.

- In a solid, atoms (or molecules) are bond together, so they cannot move freely but they can only vibrate around their fixed position.

- As the solid is heated, more energy is provided to the atoms (molecules), so they begin vibrating faster and faster as the solid is heated

- When the temperature of the solid reaches the melting point, the atoms (molecules) are vibrating fast enough to break the bonds between each other. During this phase, the temperature of the solid does not increase, because all the energy provided is used to break the molecular bonds

- When all the bonds are broken, particles are free to move, so the solid has turned into a liquid

This process (melting of a solid substance) is a physical change, not a chemical change, because the chemical composition of the substance does not change, but only the form of the substance changes.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
