amorphous
without a clearly defined shape or form
Archimedes' principle
the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
brittleness
A material is brittle if, when subjected to stress, it breaks without significant plastic deformation
buoyancy
the ability or tendency to float in water or air or some other fluid.
chemical properties
a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed
crystalline
having the structure and form of a crystal; composed of crystals.
ductility
is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.
elasticity
the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.
fluid
a substance that has no fixed shape and yields easily to external pressure; a gas or (especially) a liquid.
hardness
the quality or condition of being hard
malleability
the quality of something that can be shaped into something else without breaking
physical properties
any property that is measurable, whose value describes a state of a physical system
pressure
the continuous physical force exerted on or against an object by something in contact with it.
strength
the quality or state of being strong, in particular.
tensile strength
the resistance of a material to breaking under tension.
thermal expansion
the tendency of matter to change in shape, area, and volume in response to a change in temperature
viscosity
the state of being thick, sticky, and semifluid in consistency, due to internal friction.
