Charisse Brittney Ann Vicente __________________ THE SCIENTIFIC METHOD: IDENTIFYING WHICH LIQUID EVAPORATES FASTER I. Objectives To know the step-by-step procedure in conducting an experiment To determine how the process of scientific method helps us to solve a certain problem To identify which liquid evaporates faster. II. Science Concept Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. The rate of evaporation is dependent

Richard Landolfi Due Date:11/1 Purpose the purpose of this lab is to determine the freezing and melting temperature of water. Freezing temperature‚ the temperature at which a substance turns from a liquid to a solid‚ and melting temperature‚ the temperature at which a substance turns from a solid to a liquid. Hypothesis If the water is at a low temperature then it will freeze. If it is at a high temperature then it will melt

Writing of Lab Reports __________________________________________________________________________ W hy should I bother writing lab reports in the correct way?” The Foundation Programme is designed to prepare you for undergraduate studies at UTAR which will require the writing of lab reports all years generally. At the end of your third year‚ you may have an opportunity to work on scientific projects which will culminate in an official scientific report. Depending on the quality of your report

1 gram of an impure‚ unknown substance solid. Make sure to stir the mixture before measuring the sample; record the mixture’s code in the data section. 2. Add approx. 25-50 mL of water and several boiling chips to a 125 mL Erlenmeyer flask and heat the water to a gentle boil using a hotplate. 3. On a second hotplate‚ place a 125 mL Erlenmeyer flask containing the one gram of unknown solid along with a boiling chip. 4. Using a ring clamp‚ slowly pour approx. 5-10 mL of boiling water into the flask

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

The order that the liquids were in was blue‚ orange‚ green‚ yellow‚ and red. On our first trial‚ we only put in blue‚ green‚ red‚ and yellow mixtures inside the test tube. Before we even put in the orange solution‚ the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings
