3-

When energy is added ; the particles move faster, and this increases the kinetic
energy enough for the particles to over come the attraction forces between them
causing the particles to move farther apart to change the state of matter.

When energy is removed ; the particles move slower, and this decreases the
kinetic energy enough for the particles to come closer that increases the
attraction forces between them causing a change in state of matter.

5-a) How is the arrangement of particles in a liquid different from the
arrangement in a solid?

b) How is the arrangement of particles in a solid different from the arrangement
in a gas?

7-a) No definite shape and no definite volume, are
properties of_______________.

b) -What are the properties of a solid?

Gases

Definite shape and definite volume

The space the object takes up

solids

gases

Yes, as we remove energy particles will
slow down , Kinetic energy will
decrease particles will come closer
together and that will increase the
attraction forces between the particles
causing the change in state from gas to
solid

No , adding mass does not
change the state of matter from
gas to a solid.
