Describe what happens to the particles in the metal lid when it is run under hot water why does this trick allow the lid to be removed more easily?

The heat causes the metal to expand making the lid slightly bigger so that it breaks contact with the jar.
That's what it does, how it does it I believe is this. Heat causes the atoms in the metal to move faster or to have more energy. The more energy something has, the more room each atom needs to function. That may be simplistic, but I think that is the idea.

Can the particles in a mixture be easily separated?
Yes they can be easily separated.
Are the particles in a suspension larger than the particles of a solution but are yet to small to be easily seen?
Particles in a suspension are larger than the particles of a solution, but they are not always so small that they cannot be easily seen with the eye.
What happens to kenitic energy of the particles when a solid changes to a gas?
Kinetic energy is possessed by virtue of the motion of particles. In solids, particles are tightly packed, so the can not move easily(hence the rigidity). In gases, particles are loosely packed, so they can move more freely(hence its ability to flow). Therefore, KE of particles increases when a solid changes to gas.
Why do liquids flow easily while solids do not?
The particles in quids are more malleable/ easily shaped, since they aren't as close together as particles in solids.
Causes particles to vibrate in place?
the thermal energy is what causes the particles to vibrate.

Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
Do avocados have strings?
No, they have no strings. They have a slightly hard outer peel, but which is easily removed, and an inner pit, which is quite hard, but is also easily removed.
Which particles can wind move most easily?
SAND
What is a mixture where the particles can be easily seen and separated?
