what is hardness and examples of it
the ability of a material to resist deformation
Wood
Stone
define elasticity and examples of it
when something return to their original shape after the stress that had caused the deformation is no longer applied.
define Plasticity and examples of it
plasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation.
metals, soils, rocks, concrete, and foams.
define Malleability and examples of it
Malleability describes the property of a metal’s ability to be distorted below compression.
gold, iron, aluminium, copper, silver and lead
define Ductility and examples of it
Ductility is the ability of a material to be drawn or plastically deformed without fracture.
Wire hammered and bent without breaking.
define lustre and examples of it
the appearance of a mineral surface in terms of its light-reflective qualities.
A Dimond
gold
Compare the properties of solids, liquids and gases by referring to their shape, volume and compressibility.
Solid- a solid holds its shape meaning it’s volume is as big as the object and it is not able to be compressed
Liquid- mould to the shape of the container it’s in, the volume is how much of the container it fills and you cant compress it.
Gas- floats around in the air freely has no fixed volume and it can be compressed,
Describe the kinetic theory of matter.
The kinetic theory of matter states that all matter is made of small particles that are in random motion and that have space between them.
Use the kinetic theory of matter to explain the difference between solids, liquids and gases.
Solids- the particles are close to together and movement is hard to detect
Liquids- the partials are a medium distance apart and move at a medium speed
Gas- the particles are far apart and they move fast.
List three non-Newtonian fluids and describe their properties.
Quicksand- is made up of water and sand
Oobleck- cornflower and water
Silly putty- silicone and colour pigments
Describe one difference between BECs and plasmas. List two applications of plasmas.
plasma is extreem heat and bec is extreem coolness
