A group of students is tasked with developing a checklist for determining whether a material undergoes a chemical or physical change. The students make a preliminary list of properties that they can test and classify each as either a chemical or physical property.
Chemical Property Physical Property
bubbles when treated with acid color
burns when placed in a candle flame odor
density hardness
boiling point mass
dissolves in water melting point
Several other students in the class claim that the checklist is incorrect.
What change should the group make to the checklist to correct their mistake?
Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.
Boiling point and density should be moved to the physical property side of the list, and hardness and mass should be moved to the chemical property side of the list.
Dissolves in water and boiling point should be moved to the physical property side of the list, and odor and mass should be moved to the chemical property side of the list.
Density and boiling point should be moved to the physical property side of the list.
