Question

3-4 examples of random errors plzzzzz

Answer 1

1. Errors in judgment of an observer when reading the scale of a measuring device to the smallest division.2. Unpredictable fluctuations in line voltage, temperature, or mechanical vibrations of equipment.3. Suppose,you wanted to collect 25 mL of a solution. You could use a beaker, a graduated cylinder, or a buret. Volume measurements made with a 50-mL beaker are accurate to within 5 mL. In other words, you would be as likely to obtain 20 mL of solution (5 mL too little) as 30 mL (5 mL too much). You could decrease the amount of error by using a graduated cylinder, which is capable of measurements to within 1 mL. The error could be decreased even further by using a buret, which is capable of delivering a volume to within 1 drop, or 0.05 mL.
