Question

mrs. franklin loves teaching science and thinks about it all the time. while walking one day, she steps on a warm, fresh piece of used gum. the gum flattens and sticks to her shoe. when she lifts her foot, she sees long strings of gum between her shoe and the sidewalk. she thinks, \what a great demonstration of the properties of metals!\ what properties of metals would mrs. franklin most likely teach about with this demonstration? conductivity and luster ductility and malleability malleability and reactivity conductivity and ductility

Explanation:

• Malleability is the ability of a material to be flattened or deformed without breaking. The gum flattens when stepped on, showing malleability.
• Ductility is the ability of a material to be drawn into thin wires or strings. The long strings of gum between the shoe and the sidewalk show ductility.
• Conductivity (ability to conduct heat or electricity) and luster (shine) are not shown here. Reactivity (how a substance reacts chemically) is also not demonstrated.

Answer:

ductility and malleability
