liquid nitrogen experiment in finding the Latent heat of the substance. We isolated two parts of the experiment in order to find out how much evaporation of the liquid nitrogen was from the surroundings B and how much evaporation from the electricity G. 1. When a substance is undergoing a phase transition‚ more heat (energy) is being added to the Substance but its temperature (a way of measuring its energy) is not changing. Where does this Energy go if it does not go into heating up the substance?

Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:

Civil Engineering Department‚ College of Engineering‚ Adamson University Abstract The purpose of this experiment is to determine the Latent Heat of Fusion of ice. In this experiment‚ the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). Introduction When a substance changes phase

regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC voltage‚ from the mains supply is initially stepped down to the desired voltage‚ which is then rectified to be applied to the input terminal of the voltage regulator

Simple Stimulus Learning Lauren N. Jones Psychology 550 February 28‚ 2011 Dr. Rachel Needle Simple Stimulus Learning “Stimulus learning is a relatively permanent change in behavior‚ or behavior repertoire which occurs as a result of experience” (Terry‚ 2009). Since there is no possible way to observe knowledge itself‚ behaviors are our only source of observing what has taken place concerning learning. Learning is an inclusion of the potential for change in behavior. This change in behavior

America today is many things: advanced‚ modern‚ influential - but is it racist? Since the birth of this great nation‚ racism existed and has continued to live through different mediums. Latent racism seeks to establish racial prejudice and discrimination through subtle forms‚ even at a subconscious level. Although latent racism is hard to prove‚ many people have made it their duty to showcase and expose forms of racism that one would not normally jump to. For example‚ in the article Occupy the Dream:
