Unit 4.4 Physical and Chemical Changes
Justify a change as either a physical or chemical process based on
bonding changes.
-
Explain why condensation of water is physical but combustion of
hydrogen is chemical.
Compare and contrast physical changes involving only IMFs (such as phase
changes) with those that involve bond breaking (such as dissolving an
ionic solid).
-
Compare melting ice to dissolving NaCl in terms of forces involved.
