Magnetic Storm This video is about the Earth’s magnetic force and its wavering. The molten iron in the earth creates the magnetic force around the earth. The magnetic force protects the earth‚ making it possible for life to exist on the planet‚ unlike other planets with weaker magnetic forces. Recently‚ though‚ scientists have discovered that the magnetic field seems to be faltering. The magnetic force starts near the South Pole and extends around the earth close to the North Pole and shields

hold on to their electrons example: glass rubbed with plastic wrap glass is above plastic wrap glass will become positive and plastic wrap will become negative Conductivity is the ability of materials to allow electrons to move freely in them Insulators: are solids‚ liquids‚ or gases that resist or block the movement of electrons Conductors: are materials that allow electrons to move freely. Law of Attraction: states particles with opposite charges attract each other. (unlike charges attract)

Conductivity in metal-organic frameworks Metal–organic frameworks (MOFs)‚ are a class of crystalline materials whose crystal structure is made up from metal-containing clusters connected by multidentate organic linkers1‚2. MOFs are attracting considerable attention due to the possible rational design of crystal structures of coordination frameworks with versatile metal ions and organic ligands. In principle‚ MOFs topologies along with intermolecular distances between various building blocks can be

Biology Coursework Practical Heat Loss The aim of this practical is to find to what extent does the surface area to volume ratio of an object affect the rate of heat loss from the object Hypothesis: As the ratio of surface area to volume of an object decreases the rate of heat loss from the object will also decrease. Objects with the same surface area to volume ratios loose heat at the same rate so long as there are not other variables involved. Background Knowledge: The surface area

precipitation. Changes in melting can occur as a result of increased average annual air temperatures‚ and/or changes in the solar radiation. Melting will be affected if the glacier is covered by moraine‚ dust‚ or soot particles (increases heating‚ or an insulator).

LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy

bomb confines the reaction mixture to a fixed volume‚ the reaction is said to occur at constant volume. The other‚ much simpler and the calorimeter you are most likely to encounter is the coffee-cup calorimeter. This uses Styrofoam‚ a good heat insulator‚ for very minimal transfer of heat between the cup and the surrounding air. The reaction in the calorimeter occurs under constant pressure of the atmosphere.2 Both are isolated—it does not permit any exchange of matter and energy—and adiabatic—there

Design technique of P-type CMOS circuit for gate-leakage Reduction in deep submicron Aneesha R1‚ Shabnoor Naaz M2 8th Semester‚ E&C Dept‚ BIT Mangalore 1anee.star@ymail.com 2naazshaik.44@gmail.com Abstract— Before the CMOS process is scaled into deep sub-micron process‚ dynamic energy loss has always dominated power dissipation‚ while leakage power is little. The aggressive scaling of device dimensions and threshold voltage has significantly increased leakage current exponentially‚ thus the
