In layman’s terms, it is simply a measure of the tendency of the solution molecules to escape by entering the gas phase. Trial 1 Boiling

Keep in mind that too much detail is generally unnecessary and might swamp the reader.Boiling point experiment General instructions to write the RESULTS section: – Write this section in Past Tense and First Person Singular – Limit to the facts and avoid interpretations What you SHOULD NOT include in the RESULTS section: – A paragraph that list ALL the results obtaine – A paragraph with a description of the procedure or methods used in the experiment – Your hypothesis and predictions of the results – Any analysis of the results obtained – Do NOT restate the Hypothesis – Do NOT describe Methods What you SHOULD include in the RESULTS section: 1. B) HOW TO WRITE THE “INTRODUCTION” SECTION The Introduction informs the reader WHY you made the study. literature value or the measured value of a known sample). Otherwise, they will be returned to the student ungraded and you will have a zero in this assignment.

It is directly proportional to the molal concentration of the solution. Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. selina karim 2694784 experiment title: melting point lab partners: samantha and mackenzie goals: to observe the proper method of obtaining melting point. • Although you did the experiment per group and, thus, all the members of the group obtained the same results, each student must write his or her own Lab Report (see “plagiarism”, in the syllabus).Boiling point experiment   If two lab reports are identical or too similar, both students will a zero (0) in this assignment. – The question that the initial observation generated: What observation or question stimulated you to perform these experiments? Use these terms as headings to identify each section. Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. There is one category of properties that can only be applied to solutions; these are known as The boiling point of a solvent will increase when a solute is dissolved in it.

This happens because of the displacement of solvent molecules by the solute. It also depends on what the solute is. What background information relates to the question? A liquid boils when its vapor pressure is equal to the air pressure.A solvent’s vapor pressure will lower when a solute is added. Present your data clearly, sometimes summarized in a table. – A clear, explanatory hypothesis that you tested (an educated guess ) HOW TO WRITE THE “RESULTS” SECTION In the Results section, you tell the reader what did you find (measure, count) with your experiment. – Titles such as “Lab Report on Salt” or “Boiling Point Experiment” are unacceptable because are incomplete and does not include your findings. Discussion point 3: Modern theories of boiling In the traditional theory of boiling in physics and physical chemistry, the boundary between the liquid state and the gas state is sharply defined as the line on which the vapor pressure (function of temperature) reaches the level of the external pressure.

CONCLUSION I conclude that the boiling point of water is in fact affected by the solutes added to it. This means that some of the of solvent molecules at the surface of the liquid are replaced by the solute; it can occur in both electrolytic and non-electrolytic solutions. This particular resource used the following sources: boiling point can be compared to known values (e.g. Overall Average Value of Density = (0.802 g/mL + 0.7917 g/mL + 0.7901 g/mL)/3 = 0.7946 g/mL In the second part of experiment, the unknown liquid is determine by checking it’s boiling point by performing three trial.
