Lab 1 “Laboratory Techniques and Measurements” A. Water boils at 100C at sea level. If the water in this experiment did not boil at 100 C‚ what could be the reason? * We’re not at sea level; the pressure could be lower or higher. B. While heating two different samples of water at sea level‚ one boils at 102C and one boils at 99.2C. Calculate the percent error for each sample from the theoretical 100C. (show your work) * 1st Sample: 1.96% error * 2nd Sample: 0.81% error

Title: Laboratory Techniques & Measurements Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume‚ mass‚ length‚ and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions. Procedure: I used a ruler‚ thermometer‚ and scale to take measurements. I used a graduated cylinder‚ short step pipet‚ scale‚ and ruler to determine volume and density. I used a

The Laboratory’ ’The Laboratory’ by Robert Browning is a dramatic monologue that tells the story of a woman’s plot to murder her romantic rival. The form in which Browning has written this poem subtly reveal aspects of the female speaker whilst allowing the reader to make their own personal judgement on her behaviour and character‚ which would commonly be that she is a jealous‚ obsessed‚ blood-thirsty and sadistic woman. The speaker in the poem demonstrates signs of insanity and instability
