what is malleability?
the amount of hammering and shapinga material can withstand without breaking, splitting or cracking. Malleability is particulary desireable in metals
what is ferrous metals?
ferrous metals contain iron, such as steel and cast iron.
what are non ferrous metals?
non ferrous metals are those that do not contain iron and they do not rust.
what is fireclay?

what is compressive strength?
the maximum force a material can withstand when being crushed.
what is elasticity?
the length that a material can be stretched.
what is heaviness?
the denseness of a material. A dense material will be heavy in relation.
what is strength?
the measure of how materials withstand heavy loads without breaking.
what is heat and electrical conductivity?
the measure of how well a material conducts heat or electricity
what type of water corrodes pipe work?

how is soldering able to run a pipe?
capillary action
what are the two types of plastic categorys?
thermoplastics ,thermo-setting plastic
what is sensible heat?
when heat is directly applied to water,its temperature will rise untill it reaches his boiling point.
what is latent heat?
changes of state are also a resullt to heat added but here, the added heat leads to a change.
give 3 examples of thermal conductivity materials?
silver ,gold ,copper
what are natural gas?
natural gas is the most widely used fuel for homes and business heating and cooking in the uk.
what is TIN is it a ferrous or non ferrous?

what is third class lever?
a third class lever is one where the effort is between the fulcrum and the load.
what is the property of solid?
solids have a fixed shape and cannot flow.
what is second class lever?
a second class lever is one where the load is between the fulcrum and the effort.
what is the property of liquids?
liquids flow and take there container
what is the property of gases?
gasses flow and take the shape off their container
what is radiation?
all objects will transmit and receive heat in the form off thermal radiation
what are ferrous metals?
ferrous metals contains iron.
what are non ferrous metals?
non-ferrous metals are those that do not contain iron.
