Problem 6P

If you drop a piece of ice on a hard surface, the energy of impact will melt some of the ice. The higher it drops, the more ice will melt upon impact. Show that to completely melt a block of ice that falls without air drag, it should ideally be dropped from a height of 34 km. [?Hint: Equate the joules of gravitational potential energy to the product of the mass of ice and its heat of fusion (in SI units, 335,000 J/kg). Do you see why the answer doesn’t depend on mass?]

General Chemistry: Chapter 1 Reading Notes By Madelyne Crawford, August 25 The following notes were acquired from Chemistry: A Molecular Approach Textbook by Nivaldo J Tro. The reading was to be completed by Monday, August 29. Overview/Review of Chapter 1  The main goal of chemistry is to analyze and study the behavior of matter by understanding the behavior of atoms and molecules  The scientific approach to knowledge is based on observation and experiments  Qualitative vs. quantitative: o Qualitative describes how a process happens o Quantitative measures something about the process  A hypothesis is an interpretation of observations that explains scientific findings
