Answer:
B, C, E, G
Explanation:
B - As particles are heated, they gain heat energy (or thermal energy, Q) from whatever the source may be.
C - Thermal energy particles gain is converted into kinetic, and the more KE/kinetic energy particles have, the more energy they have to move around.
E - When particles have more energy to move around more, they slide and move past each other and create more space; hence, they become further apart.
G - Eventually, particles will have enough energy and will move around so much that the attracting forces holding them together in the first place will be lesser than the particle's energy to break free and move from the attractive forces.
