Properties of paper include the thickness, weight, texture, folding endurance, strength and size of the paper. Some grades of paper tear easily, while others resist tearing. The moisture retention capacity is another important property of paper. Some grades of paper dry very quickly and do not absorb moisture.Know More
Blotting paper is a type of paper used to absorb ink because it has a high moisture retention capacity and can absorb liquids. Cardboard paper is hard and difficult to fold. Paper used for writing is often soft, smooth, glossy and lightweight.
Paper is made from wood pulp and is primarily used for writing, printing and packaging. The making of paper began in China almost 2,000 years ago.Learn more about Chemistry
Physical properties are characteristics of matter that can be observed without making any changes to the chemical composition of that given matter. In academic contexts, physical properties are often contrasted with chemical properties.Full Answer >
Aluminum is a lightweight, ductile metal with a density roughly one-third that of steel. Despite its low density, aluminum is strong for its weight and can easily be alloyed with other metals to produce useful compounds.Full Answer >
Solids, liquids and gases are the three main phases of matter. Solids have a fixed crystalline structure, whereas liquids and gases are more free-flowing. The phase of matter that a given substance exhibits depends on temperature and pressure.Full Answer >
Thermoplastics are a subset of plastics that can be re-shaped with the application of pressure and heat multiple times. Different types of thermoplastics have additional properties that make them especially well-suited to different jobs, but all thermoplastics share the same characteristic of flexibility when exposed to heat and force.Full Answer >
