While ms. brown's science class is studying changes in particle motion during phase changes, they add a few pieces of dry ice to a flask and cover it with a balloon. after a few minutes they observed the balloon starting to inflate. predict what will happen if they put the flask with the inflated balloon onto a hot plate and raise its temperature from room temperature to 40 °c.
a) no change occurs.
b) the balloon will deflate.
c) the dry ice precipitates.
d) the balloon inflates further.

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?

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
