Experiments performed to reveal the structure of atoms led scientists to conclude that an atom's (1) positive charge is evenly distributed
throughout its volume
(2) negative charge is mainly concentrated in its
nucleus
(3) mass is evenly distributed throughout its
volume
(4) volume is mainly unoccupied

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic

What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume? explain your answer.
