Chemical Engineering Chemical Engineering is the branch of engineering concerned with the design and operation of industrial chemical plants. I have been interested in chemical engineering at a young age because I have plenty of engineers in my family. I was influenced by my family to go into engineering because I witnessed how much my family worked‚ and how much it is able to support my family. Becoming an engineer ensures me of a stable job‚ and I will be financially stable. Chemical engineering

1. You don’t have to be a chem whiz * Chemical engineering requires a basic understanding of chemistry‚ physics‚ math. You’re not required to memorize formulas‚ it’s more important to understand the principles and learn how to apply them to solve a problem/improve status quo. However after a few semesters‚ your brain WILLremember many formulas! * You do need to be analytical and have the ability to think critically. You must be able to look at the problem from a bigger viewpoint but

Theme : Electrical Sector and Chemical Engineer a) “The Chemical Engineer – His Role in Electrical Manufacturing” by N.R. Maleady The article is about the role of chemical engineer in manufacturing transformers in the electrical manufacturing sector. The important components of the transformer are copper wire‚ cellulosic insulation‚ insulating varnish and dielectric liquid. Wire enamel or resin is the insulting structure for copper wire. The resin can either applied as a solution or in solventless

I am going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and

skin contains numerous sensory receptors which receive information from the outside environment. The sensory receptors of the skin are concerned with at least five different senses: pain‚ heat‚ cold‚ touch‚ and pressure. The five are usually grouped together as the single sense of touch in the classification of the five senses of the whole human body. The sensory receptors vary greatly in terms of structure. For example‚ while pain receptors are simply unmyelinated terminal branches of neurons‚
