10-26-12 3RD Block Mrs. Sneed Hot Air Balloon Report Hot air balloons fill up slowly and then rise in the sky. Two important principles of physics: the ideal gas law and Archimedes’ principle are the reasons hot air balloons fly. The mathematical relationship between the volume pressure and the temperature of a gas is called the ideal gas law. When a gas is heated‚ as in a hot air balloon‚ then its volume will increase. However‚ there is a heater located in the balloon’s basket that heats the

To make a standard solution Apparatus: Volumetric flask Method: 1) 2.4g to 2.5g of sulphamic acid was weighed out‚ firstly by weighing the container and the sulphamic acid together‚ then pouring the sulphamic acid into a beaker. The container was then weighed again and the initial weight and the weight of the container alone were subtracted from one another to provide the mass of the sulphamic acid. 2) The sulphamic acid was then dissolved in 50cm³ of distilled water‚ using a glass

Walter A. Shewhart March 18‚ 1981- March 11‚ 1967 Walter Andrew Shewhart is regarded by many as the “father of statistical quality control.” He was born in New Canton‚ Illinois on March 18‚ 1891 to Anton and Esta Barney Shewhart. Walter attained his bachelor’s and master’s from the University of Illinois in physics and graduated with is PhD from UC Berkely in 1917. Throughout his adulthood‚ he was a professor at both universities and ran the physics department at the Wisconsin Normal School

Fashion blogs are bad Did you know that a fashion blog is actually a drug‚ well it’s not classified as a drug but you get addicted to them. You stop seeing the importance in life such as news‚ disasters and so on. All that’s on your mind is fashion‚ shoes and makeup. Fashion blogs also makes you spend money. I think fashion blogs are bad and here comes some reasons. First of all fashion blogs are only nonsense. All there is to read are clothes‚ makeup‚ bags and shoes. All their readers

Determining the Density of Plastics 1) Introduction ⦁ a) Purpose: Determine density of different plastics ⦁ b) Hypothesis: If density is related to the ratio of mass to volume‚ then density can be calculated by using the formula D=M/V. i. c) Background: Density is the physical property that can be used to help identify substances. D=M/V. mass= found using a balanc and labeled in grams and volume=graduated cylinder or taking ( lxwxh ) measured in mL or cm3 2) Materials ⦁ a) List -graduated

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

Cartesian Diver The purpose of the Cartesian diver is to demonstrate the compressibility of a gas‚ the incompressibility of water‚ Boyle’s law‚ Pascal’s law‚ and Archimedes’ law. Boyle’s Law states that under conditions of constant temperature and quantity‚ there is an inverse relationship between the volume and pressure for an ideal gas. Pascal’s Law states that if pressure is applied to a non-flowing fluid in a container‚ then that pressure is transmitted equally in all directions within the

Today most people think of ships as common every day tools that don’t take much to understand. One builds a hull and some little structuring later and bam you have a ship. But ship building is much more than taking some metal and building a floating structure. It takes years of understanding and research to build such a vessel. Mankind has been building ships for centuries but it was not until the 17th century that Archimedes‚ a great Greek Mathmatitions‚ ideas were used and studied closely.
