How does the arrangement of particles in a substance change when a substance melts?
Changes very easy
Is the speed of the particles in a substance changes when the temperature changes?
Yes, in fact, particle movement is what heat is.
How does the motion of the particles change when the changes from a solid to a liquid to a gas?
water changing to a solid: freezing movement of particles: vibration in fixed positions. arrangement: fixed positions (bonds between every particle). moving closer together water as a liquid: movement of particles: move about (slide past each other) arrangement: close together with no regular arrangement water to gas: boiling movement of particles: free/random movement at high speeds. arrangement: particles move further apart with no bonds between particles.

Describe how the motion and arrangements of particles change as a substance freezes?
The arrangement changes because the freezing point. When something freezes it changes into a new substance and that is arranging it into a chemical change.
A substance changes from a solid to a liquid?
You mean if a substance can go from solid to liquid? Of course, take the ice cubes out of the freezer and you'll see it happening. Do you mean that when such process occurs, does the substance changes? No, only the grouping and movement of particles in it.
What happens to the kinetic energy of the particles of a substance changes from liqiud to a gas?
When a substance changes from a liquid to a gas, the kinetic energy of its particles increases.
What speed of the particles in a substance change when the what changes?
electrons
The speed of the particles in a substance change when what changes?
electrons
Is melting point classified as a chemical property or a physical property?
physical. melting does not change the substance; it only changes the state of matter (or the movement of particles).
The addition or loss of thermal energy changes the arrangement of the particles during what?
A change in state
The addition or loss of thermal energy changes the arrangement of the particles during?
a change of state
