3) Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word "electricity" is sometimes used to mean "electrical energy".
Answer:
A1.)Mineral oil is a highly purified, lightweight ingredient used in baby lotions, cold creams, ointments and many other cosmetic and personal care products, due to its ability to help reduce water loss from skin and keep it moisturized.
The highly refined, purified mineral oil found in cosmetic and skincare products is noncomedogenic, meaning it does not clog pores. Because it also is an inert, stable compound, mineral oil is an ingredient in products for use on sensitive skin, because of its relatively low likelihood of causing a skin reaction, or of spoiling in hot, humid climates.
A2.) As the minerals are exhaustible and non-renewable natural resources, their exploitation has to be done systematically and scientifically for sustenance. Augmentation of resources through improved mining and beneficiation methods and utilization of low-grade ores needs to be done to conserve minerals. These aspects constitute the essentials of the National Mineral Policy of India.
One method of conserving mineral resources is recycling. The increased need for mineral resources can partly be met by conservation. Conservation means using material wisely. One method of conserving mineral resources is recycling. Renewable resources have the capacity to get replaced by recycling through natural cycles.
