In the experiment of determining melting point why each time fresh paraffin liquid should be taken?
Each time fresh paraffin liquid should be taken in the experiment of determining melting point to ensure accurate and consistent results. Reusing the same sample may introduce impurities or contaminants, leading to inaccurate melting point measurements. Using fresh paraffin liquid each time helps to eliminate any potential variables that could affect the melting point determination.

Can examples be given to show that plastics are noncorrosive in nature?
When we go to buy any food item we generally use to carry them in plastic as plasctic do not reacts with food items as well as air and water.
How plastics are noncorrosive in nature?
Plastics are made from large polymers containing strong bonds, so theyre pretty unreactive. like plastic tubs in microwaves, if it was fairly reactive and weak, it might have melted or exploded.
What is the origin of the word freon?
Freon is DuPont's trade name for its odorless, colorless, nonflammable, and noncorrosive chlorofluorocarbon and hydrochlorofluorocarbon refrigerants. In 1928, Thomas Midgley, Jr. aided by Charles Franklin Kettering invented a "miracle compound" called Freon. Freon represents several different chlorofluorocarbons, or CFCs, which are used in commerce and industry.
