This question is probably simple, but I am just double-checking for chemistry's sake.
Classify each of the following as a physical or chemical change.
a. dissolving salt in water - chemical (Is this right?)
b. boiling water - physical
c. cooking an egg - chemical
d. rusting of iron - chemical
e. burning wood - chemical
f. evaporation of water - physical
g. getting a suntan - Er, I am uncertain of how to label this . . .Is it chemical since UV radiation stimulates melanocyte cells?
Thanks. :-)
