To connect this demonstration with today's lesson, I explain: Yesterday you began measuring and observing physical properties of matter. You learned how the properties of matter help us distinguish one substance from another. Today, we are going to take this one step further by further exploring the properties of different states of matter.
Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. Intensive properties, such as density and color, do not depend on the amount of matter. Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance’s chemical identity.

The lowest fatigue properties have been obtained for the polyester/glass-PUF-polyester/glass sandwich panel specimens. Better performance of the epoxy/glass-PUF-epoxy/glass sandwich panels is most likely due to the superior properties of the outer thin skins. Most of the specimens fail within the foam region and not at the skin level.
For this study commercially available, flexible, non-flame retardant polyether polyurethane foam was used in the experimental fire tests 1. Material properties were obtained from small-scale (micro-calorimeter) experiments performed 1 and from literature. Table 1. Material Properties of PUF
Classification of Foam Structures. Following from: Highly porous cellular foams. In order to correctly evaluate the mechanical properties, as well as the thermal properties (such as the conductive and radiative properties), the foam structure must be modeled as close as possible to real three-dimensional (3D) foam geometry.
Properties. Polyurethanes (PUR) are one of the largest classes of polymers with properties that can be tailored over a wide range for a large number of application. They can be thermosetting or thermoplastic, rigid and hard or flexible and soft.

The physical properties of a series of model protein, surfactant and protein/surfactant foams were enumerated and investigated using foam conductivity, surface tension, preliminary surface rheology and bulk viscosity measurements. Images of various predetermined stages in the evolution of foam samples were obtained.
However, a number of comparative studies have highlighted that foam dressings are superior to hydrocolloids in terms of exudate management and in-use characteristics (such as ease of use, ease of removal and conformability) in the treatment of exuding wounds although other studies report no real difference between the two product types.
For development of eco-friendly packaging foam from pomelo peel, physical and mechanical properties of the pomelo peel and effects of pomelo varieties, namely Kao-Nampueng, Thong-Dee, and Kao-Pan, on their properties were investigated.
Classifying Polygons Closed shapes or figures in a plane with three or more sides are called polygons. Alternatively, a polygon can be defined as a closed planar figure that is the union of a finite number of line segments.
