6 report Anita Dey Thursday 8am Abstract: We recently performed a 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

lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

Mr. Enrico Mantoli found merciless death while walking on the highway of Wells. Officer Sam Woods had found Mantoli’s body lying down on the pavement motionless‚ around 2 am just last night‚ while he was on his midnight patrol. Suspect is nowhere to be found‚ our respected man Mr. Mantoli has been struck from the behind of his head by a blunt instrument‚ leaving him to his death. Mantoli was the host of the upcoming music festival‚ which many of us know and heard of. But franticly Mantoli‚ was left

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:

Ailine Veiga Question: what is the heat of fusion of ice? Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass

Specific Heat Lab Objective: Find the specific heat of the unknown metal given using calorimetry. Background Theory: In every reaction‚ energy is transferred between a system and its environment. A system encompasses the substances that are involved in a reaction‚ and everything else in the universe other than the system is called the environment. The standard SI unit of energy is Joules (J). Temperature is the level of excitement of the atoms in a substance. In most cases‚ energy is
