Question

Give one application of (i) Mineral oil (ii) Varnish (iii) Synthetic oil (iv) Vegetable oil.

Answer 1

Here’s an application for each:

1. Mineral Oil  
   

   Application: Insulating Oil in Transformers  
   Mineral oil is widely used as an insulating and cooling medium in electrical transformers. It helps to dissipate heat and provides electrical insulation between the windings of the transformer.

1. Varnish  
   

   Application: Coating for Electrical Motors and Generators  
   Varnish is used to insulate and protect the windings of electrical motors and generators. It prevents moisture and contaminants from causing damage to the electrical components and enhances the durability of the equipment.

1. Synthetic Oil  
   

   Application: Lubrication in High-Performance Engines  
   Synthetic oil is commonly used in high-performance engines, like those in modern cars or aircraft. It provides better lubrication at high temperatures and extreme pressures, reducing wear and improving engine efficiency.

1. Vegetable Oil  
   

   Application: Biodiesel Production  
   Vegetable oil is used in the production of biodiesel, an eco-friendly alternative to petroleum diesel. It can be processed into biodiesel by a chemical process called transesterification and used in diesel engines.
