OC. Which graph 7. (2 pts) We studied problems involving a brass sphere passing through a brass ring. If the brass ring is placed in liquid nitrogen and cooled to about -80 .C (i.e. 80 degrees below zero), the sphere will no longer pass through the ring. The inference that follows is that the brass ring was involved in thermal contraction. Carefully draw two particle-level (10 million magnification Ultra scope) microscopic models of the brass-one at room temperature (20 .C) and one at -80 .C, i.e., -80 degrees below zero. Brass particles at 20 deg Celsius Brass particles at - 80 deg Celsius ture both acetone (common in nail polish remover) and ethanol atone is a
