Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the quantity

Paper Cone Investigation Lisa Han 10MF Design Research Question: This investigation will determine how the sector sizes of the piece of the filter paper affect the terminal velocity for the cone to fall. The following will be kept constant meter ruler‚ stopwatch‚ and filter paper. Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area

Purpose Determine which kinds of reactions involve electron transfer as the driving force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple

Mammalian Kidney Investigation Background Information: The kidneys are dark red bean -shaped organs that are a very important pair of organs that perform many functions. The kidneys have a convex side and a concave side. They are each about the size of a fist. The kidneys are located near the middle back of a human‚ just below the rib cage‚ one on each side of the spine. One kidney is located below the spleen on the left side of the body‚ whereas the other kidney is located just below the liver

Samarpan Rai 30/11/012 Physics HL Investigation on Young Modulus Young’s modulus‚ also known as the tensile modulus‚ is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. Young’s modulus is named after Thomas Young‚ the 19th century British scientist. It is a very important concept that categorizes metals on basis of their elasticity. In the last lab‚ we were asked to find out the Young Modulus of two wires: Copper and Steel. I worked on Copper
