Tensile Property Testing of Plastics
The ability to resist breaking under tensile stress is one of the most important and widely measured properties of materials used in structural applications. The force per unit area (MPa or psi) required to break a material in such a manner is the ultimate tensile strength or tensile strength at break. The rate at which a sample is pulled apart

Physical properties of materials Properties of materials
Chapter overview. 2 weeks. This chapter builds on the chapters about the properties of materials in Gr. 5 and 6 Matter and Materials. Some of the properties learners encountered in the earlier grades are revisited but now we start placing greater emphasis on how properties that may be desirable in a consumer product may become undesirable properties when that product turns to waste.

Melting Point and Freezing Point. Pure crystalline solids have a characteristic melting point the temperature at which the solid melts to become a liquid.The transition between the solid and the liquid is so sharp for small samples of a pure substance that melting points can be measured to 0.1 o C. The melting point of solid oxygen for example is -218.4 o C.

R-values of Insulation and Other Building Materials
In construction the R-value is the measurement of a material s capacity to resist heat flow from one side to the other. In simple terms R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive. For instance if you have a material with an R-value of 12 attached to another

Band Theory of Electrical Conductivity Boundless Chemistry
In most materials the direct current is proportional to the voltage (as determined by Ohm s law) provided the temperature remains constant and the material remains in the same shape and state. Most familiar conductors are metallic. Copper is the most common material used for electrical wiring. Silver is the best conductor but it is expensive.
