The differential cross section for scattering 6.5-mev alpha particles at 120° off a silver nucleus is about 0.5 barns/sr. if a total of 10 10 alphas impinge on a silver foil of thickness 1 itm and if we detect the scattered particles using a counter of area 0.1 mm 2 at 120° and 1 cm from the target, about how many scattered alphas should we expect to count? (silver has a specific gravity of 10.5, and atomic mass of 108.) 14.12 ***

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
