I'd say it stands for Poly ethylene which is a tough, light, flexible synthetic resin made by polymerizing ethylene.
Chemistry can be divided into five traditional areas of study: organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry. These subdisciplines focus on different aspects of chemistry and allow for a more specialized study of the field.
The five main branches of chemistry are organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Each branch focuses on different aspects of matter and the interactions between substances. Organic chemistry studies carbon-based compounds, inorganic chemistry focuses on non-carbon compounds, physical chemistry examines the physical properties and behavior of matter, analytical chemistry involves identifying and quantifying substances, and biochemistry studies chemical processes in living organisms.
Specialized branches of chemistry include biochemistry (study of chemical processes in living organisms), analytical chemistry (identification and quantification of substances), physical chemistry (study of how matter behaves on a molecular and atomic level), and environmental chemistry (study of chemical interactions in the environment).
There actually three(3) branches . They are :- ORGANIC ; Chemistry of carbon compounds. INORGANIC ; Chemistry of non-carbon compounds (The rest of chemistry) PHYSICAL ; Chemistry involved, with heat , light, energy, calculations, stoiciometry.
No, acetone should not be used to clean polyethylene (PE) as it can cause the material to degrade or dissolve. It is recommended to use mild soap and water or a cleaning agent specifically designed for use on PE surfaces.
