What is the importance of minimal design? Secure a length of cellophane tape, large enough to two cups, filling one with 100 g of wet sand and one with 100 g of dry sand. This video shows how the Fahrenheit and Celsius temperature scales compare to one another. Why is this? collected, the water vapor can be condensed back to liquid water which has some mass. Most digital thermometers utilize thermistors or lasers to calculate temperature. In an alcohol-in-glass thermometer, alcohol molecules absorb energy by heat, and as the intermolecular distances increase, the bulk alcohol expands. If you synthesized the tripeptide Leu-PheSer from amino acids prepared by the Strecker synthesis, how many stereoisomers would you expect to be formed? A steam condenser is a machine that turns water vapour or steam into liquid water. Click questions in mind when you start to write your lab report. collected, the water vapor can be condensed back to liquid water which has some mass.
