Some grades of paper tear easily, while others resist tearing. different set of physical and chemical properties. different set of physical and chemical properties. For example, if spherical (r = radius and ρ = density) Surface area (a) = 4π r2 Mass (m) = ρV = ρ[4πr3/3] Thus, specific surface area (s=a/m): s = 3/ρr (inversely proportional to radius) J How to approximate surface area of a clay particle ??? Chemical Change: Change in which one or more kinds of matter are transformed to new kinds of matter with altered compositions (or Chemical Reaction). In the following module we will focus on brittle fracture of ceramic materials. no. Physical properties are contrasted with chemical properties which determine the way a material behaves in a chemical reaction. 2. In chemical changes, new substances, of different chemical composition, are produced. No change in color or smell. A physical property is a characteristic of matter that is not associated with a change in its chemical composition. A filter paper will allow the water to pass through as filtrate. One or two large wide-mouthed glass jars (for example, pickle jars). Examples of Physical Properties: 1.
