Which of the following is neither a chemical change nor a physical change?

    wax melting
    a candle burning
    oil floating on water
    sea water drying up to leave a residue of salt

anonymous · Answer

oil floating on water. nothing happens to the oil or the water.
wax melting - physical (melting)
candle burning - chemical (burning)
sea water drying up - physical I think. the water evaporates and only the solid salt residue is left.
