Answer:

1.) The kinetic energy speeds up from solid to liquid to gas. A solid has the slowest moving particles, think about ice. The particles have less kinetic energy, so they keep a solid shape. A liquid has faster moving particles, think about water (melted ice). There would have to be more energy in the environment (friction, light, heat) to speed up the particles' kinetic energy. Gas has the fastest moving particles, think about steam or hot water. The particles move so fast that they can't keep a solid shape.

2.) The mass number is the sum of the number of protons and neutrons in an atom. It is a whole number. The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.
