Final answer:
A material that can be shaped or extended by physical pressure, such as hammering, exhibits the property of malleability.
Step-by-step explanation:
A material that can be shaped or extended by physical pressure, such as hammering, exhibits the property of malleability. Malleability is the ability of a material to be deformed under compression without fracturing. This property is commonly seen in metals like gold and copper, which can be hammered into thin sheets without breaking.
