Title Freezing and Melting Point Objectives 1. To gain proficiency in constructing a graph and plotting data points. 2. To determine the freezing points of a compound from the graph of decreasing temperature versus time. 3. To determine the melting points of a known and unknown compound. Introduction Physical changes are the changes in the physical properties of a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline

The Tipping point: how little things can make a big difference by Malcom Gladwell is a novel that reveals how ideas‚ messages‚ products‚ and behaviors spread‚ which is explained through three rules heavily influence the Tipping Point and are required for one to consider a scenario as the Tipping Point. The Tipping Point is described as the moment of critical mass‚ the threshold or boiling point that results in change (Gladwell‚ 2000‚ p.12). To explain the Tipping Point Gladwell informs the reader

The Effect of Boiling on the Rate of Aerobic Respiration of Germinating Peas Abstract Aerobic respiration is an enzyme mediated process during which glucose is used to make ATP to fuel the cells energy needs. Germination is one of such processes that make use of aerobic respiration and because certain factors can affect aerobic respiration‚ it would also affect germination. In this experiment‚ we examined the effects of boiling on the rate of aerobic respiration of germinating peas. Unboiled

get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding table salt to boiling water will

Title: Does elevating the head of the bed reduce the risk of ventilator-associated pneumonia (VAP)? Introduction: According to Polit and Beck (2012‚p.3) “research is a systematic review inquiry that uses disciplined methods to answer a question or solve problems. The ultimate goal of research is to develop‚ improve and expand knowledge”. Research in nursing can produce new knowledge into nursing practice‚ develop and improve methods of caring and trial the efficacy of care (Gerrish‚ K and Lacey

temperature at which movement of the specimen is observed is recorded as the pour point. INTRODUCTION In the cloud point experiment‚ waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled. Whereas‚ pour point experiment is to determine the minimum temperature of the oil which will continue

The phrase “turning point” has a lot of meanings but personally‚ for me‚ it is a moment that caused me to realize what has always been in front of me. Turning point may also mean a time at which a decisive change in a situation occurs‚ especially one with beneficial results. Recently‚ one event became the turning point of my life and my beliefs. Last Tuesday‚ our class‚ II-St. Therese watched the film “The Encounter”. That movie marked a pivotal moment in my life. It helped me realize that Jesus
