Frequently Asked Question
Q1: What does Engineering chemistry mean?
A1: Integration of advanced organic, analytical and electro-chemistry knowledge into the design curriculum of engineering is called Engineering chemistry. Students get to study and know about the design of large scale chemical manufacturing plants.
Q2: What is electro chemistry?
A2: Study of processes involved in the inter conversion of chemical energy and electrical energy is called electro chemistry.
Q3: Why and how do engineers use chemistry?
A3: Inventing economic ways of using energy and materials is the basic function of chemical engineers. The engineers utilize chemistry and engineering to turn raw materials into products which are usable like petrochemicals, industrial setting, large-scale plastics, medicine etc. Along with this, they include research and waste management.

Q5: What are the advantages of batteries?
A5: Advantages of batteries include,
- Different shapes and sizes of the batteries are available which efficiently fits the devices they power
- When it comes to weighing, batteries weigh much lighter than the other different energy equivalent secondary batteries
- There is no memory effect
- Batteries have high open circuit voltage when compared with aqueous batteries thus increasing the amount of power that can be transferred at a lower rate of current
- Batteries have a better self discharge rate.
