10.So what EXACTLY is the cause of THREE different STATES of matter?
In your explanation you must use
words such as
Molecules or Atoms
Movement
Arrangement
Kinetic energy
Closely packed
Spread out

Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed molecules and atoms .A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
