What are the characteristics of material value explain?
Material values have been defined as the tendency to place possessions and their acquisition as central in one’s life, to view possessions as a means to happiness, and as an indicator of own and others’ success (Richins and Dawson 1992).
Why is there need to know the characteristics of materials?
The main physical characteristics of matter are mass, volume, weight, density, odor, and color. It is important for them to know and understand the correct ways to handle and store types of matter. They also need to know if any types of matter will have a certain chemical reaction when mixed with other types of matter.
