Chemical changes are everywhere from everyday things such as baking to scientific things such as changing one gas into another. Physical changes are changes that can be observed with senses and change a certain property or properties to a substance but it still remains chemically the same. This can include changes in the state of matter, size and shape. Chemical changes are when the substance is changed chemically with its properties changing with it. The substance with change from one substance…

“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…

Membrane Potential in the RMP The membrane potential in the Resting Membrane Potential, or the RMP, is the little bit of voltage or electrical potential going across from the membrane of its regular resting voltage. This is caused because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

These actually work faster than fuses do. RCCBs jobs are to detect if there is a difference between neutral and live wires. This device disconnects itself when it senses a difference between the two. This is because the electric current is not balanced as it should be. Once it disconnects itself, it will be much safer as there will be a less chance for electrocution. These types of circuits are widely used where there is a need for fire protection such as lighting circuits…

school teacher and a major influence on my life. In 1878, i worked on a way to replace the gaslight and candle light on inventing a safe, inexpensive electric light to replace twas a challenge that scientists had been trying to envent a new light for over 50 years.With the help of wealthy J.P Morgan and the Vanderbilt family, I set up the Edison Electric Light Company and began…

Roller coaster engineers work with a design team in a variety of tasks concerning the construction of roller coasters. The main duties involve deciding what type of roller coaster to use, determining how to place the track, developing the controls systems and verifying that the ride is safe for the public. Generally, engineers try to make rides exciting by including special arrangements that enhance some element of the ride. Loops in the track, embankments and the use of natural scenery are some…

This substantial distinction prompts to the loss of an electron from the less electronegative particle and the pickup of that electron by the more electronegative molecule, bringing about two particles. These oppositely charged particles feel a fascination in each other, and this electrostatic fascination constitutes an ionic bond. Ionic holding happens between a nonmetal, which goes about as an electron acceptor, and a metal, which goes about as an electron contributor. Metals have few valence…

Deception in Psychological Research Psychologists Blass (2009), Milgram (1964), Zimbardo (1998), Elms (1982), Wren (1999), Forward, Canter and Kirsh (1976) yield acceptance, credibility and functionality of deception within psychological research. Baumrind (1964), Miller (1972), Greenberg (1967) and Kelman (1967, 1972) on the other hand hold contrasting views. Deception when duplicating life like scenarios removed from artificial representation, harmfulness, risk taking in order to investigate…

Atoms, ions, and isotopes are everything you eat, breathe and see. They are everywhere and everything is made up of them. The first person that aided in the discovery of the atom was Democritus in 400 BC. He is the one that named the atom. The word atom comes from the Greek word atomos which means indivisible. Aristotle which was another flossier in at that same time disagreed with him. He believed that matter could be divide infinitely without changing its properties. At that time more people…
