radiation is one of the three ways in which heat is transferred. In convection‚ heat can be exchanged from one fluid to another. In this experiment‚ a heated plate is in contact with air inside a rectangular cross section duct. The air is heated by conduction from the heated plate. The density of the air decreases as it is heated and this makes the warm air rise. Colder air‚ which in turn is less dense‚ then replaces the warmer air‚ which has risen. The plate then heats this colder air‚ which will eventually

The Absorption Spectrum of Cobalt(II) Chloride Thang Dinh Lab partner: Alex Yang CHM 151 – 102 11/17/2014 Introduction: Many compounds absorb a certain spectrum of visible light. Since Beer’s Law describe the relationship between molar absorptivity and concentration‚ one could use his equation A = kc to find the unknown concentration by the known absorptivity. The graph of absorption spectrum is represented by a linear regression. From the graph‚ one could deduct that as the concentration decreases

Abstract Precipitation hardening‚ or age hardening‚ provides one of the most widely used mechanisms for the strengthening of metal alloys. It influences some properties of the alloys such as strength‚ hardness and ductility. The purpose of this experiment was to test the effect of temperature and aging time on strength and hardness of 6060 aluminium alloy samples that have roughly similar compositions by subjecting them to different temperatures for different periods of time. The experiment showed

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

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

A Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the

Effect of colors Did you know that the color blue gives you the impression that a space is larger than it actually is in reality? It’s not the only case when colors help you juggle with their special effects. Let’s look at some of the most important issues regarding the role of chromatic combinations in the creation of a pleasant and relaxed ambiance. Suppose we have two rooms in one apartment. The two rooms are identical in size‚ but we paint the walls in two different colors: dark

Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily
