Newtons third law of motion By: Crismaily Valdez Evaluate Newton Third law of motion work ● For every action there is a equal and opposite reaction. The Introduction in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal

Combustion of Alcohols Purpose: The purpose of this investigation is to use calorimetry to determine the molar enthalpy change in the combustion of each of a series of alcohols. Question: How do the enthalpies of combustion change as the alcohol molecules become larger? Prediction: I predict the bigger the molecule the more the energy will be released. Materials: On lab sheet Procedure: On lab sheet Observation: On other page Analysis: b) i) Ethanol – q=(100g)(4.18J/g/C)(25.5C) q=10659J

WATER QUALITY AND CONTINMINANTION Introduction I. Body Paragraph #1 – Background~ Water quality is decided by assessing three classes of attributes: biological‚ chemical‚ and physical. There are criteria of water quality set for each of these three categories of properties. The standards for drinking water are developed by the Environmental Protection Agency (EPA)‚ World Health Organization (WHO) etc. All municipal (public) water supplies must be measured against these standards. Testing how

Self Heating Food and Drink Cans Heater meals – originally developed for military use – are ready-made self-heating meal packs. They can be heated in many ways – by pressing a button on the packaging‚ unwrapping and shaking the pack‚ or pouring the contents of one bag into another and waiting for a few minutes – all of which use exothermic chemical reactions. These meals can be used to motivate students to study such reactions relatively safely and without the use of a burner. Plus there is the

in its essence‚ new ways of thinking. The most powerful type of technology‚ sometimes called enabling technology‚ is a thought incarnate which enables new knowledge to find and develop news ways to know. This kind of recursive bootstrapping is how science evolves. As in every type of knowledge‚ it accrues layers of self-reference to its former state. New informational organizations are layered upon the old without displacement‚ just as in biological evolution. Our brains are good examples. We retain
