Answer: Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. ... If the Sun weren't there, the Earth would travel in a straight line. But the gravity of the Sun alters its course, causing it to travel around the Sun, in a shape very near to a circle
Gas, as the particles have the most energy, and thus move the most.
i believe the answer is, b. heat energy is continuously added at each step. As energy is added, the molecular motion/kinetic energy increases, and matter changes state. In the last state, plasma, enough energy has been added to cause the atoms to disassociate into ions.
hope this is right! :33
