Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

BEER’S LAW EXPERIMENT 3 Amanda Buchanan – September 20‚ 2015 Chemistry 1212 – Section 50 OBJECTIVES: The objectives of this experiment are to understand why and how spectroscopy is used to determine the components and concentrations of a solution‚ describe various types of spectroscopy‚ describe the visible and ultraviolet regions of the electromagnetic spectrum‚ define Beer’s law and define the relationship between absorbance and transmittance. Other learning objectives are to create a Beer’s

Newton’s Second Law How does a cart change its motion when you push and pull on it? You might think that the harder you push on a cart‚ the faster it goes. Is the cart’s velocity related to the force you apply? Or does the force just change the velocity? Also‚ what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one. A Force Sensor and an Accelerometer will let you measure the force on a cart

go over 200. Whatever the amount being‚ I will divide that in half‚ trying to use the method that the College of Lake County refers to: * Use the same subjects in both the control and experimental groups. (This is called a repeated measures design). * Match subjects on important variables (e.g.‚ for every 20 year old female in the control group there is a 20 year old female in the experimental group). * Random assignment. (Let chance decide who gets placed into which group. Thus

‘The design arguments prove God’s existence’. Assess this view. (30 marks) Design arguments‚ also sometimes known as teleological arguments‚ from the Greek ‘Telos’ for goal and ‘Logos’‚ meaning reason‚ hence reasoning for a goal or purpose and that purpose being God’s existence. These arguments endeavour to ascertain God’s existence‚ by inferring from evidence of design and purpose in the universe‚ and claim that there must have been a designer of this. Design arguments start from experience

Research Paper on Pascal’s Law Blaise Pascal’s findings and contributions to the behavior of fluid in an enclosed space have been an invaluable and important concept in fluid mechanics and its applications especially in the automotive industry‚ mechanical engineering‚ and hydraulics. Pascal’s law or the principle of transmission of fluid-pressure that was proposed by Blaise Pascal. According to Bloomfield‚ the law is a principle in fluid mechanics that states that for a particular position within
