chemical property - correct answer properties that are only observable during a
chemical change (combustibility, food digestion...)
extensive property - correct answer a property that depends upon how much matter
is being considered (mass, length, volume)
intensive property - correct answer a property that does not depend upon how much
matter is being considered (density, temperature, color)
physical change - correct answer does not alter the composition or identity of a
substance (ice melting, sugar dissolving in water)
chemical change - correct answer alters the composition or identity of the
substance(s) involved (hydrogen burns in air to form water)
energy - correct answer the capacity to do work
