Exercises
Answer the following questions. Show pertinent solutions on the blank space below.
1. Five students measure the mass of the same object as 7.998 g.
8.001 g, 8.001 g. 8.003 g, and 7.997 g. What would be the best
way to report the mass of the object?
2. The length and width of a room were found to be 12.50 + 0.01 m
and 9.63 + 0.0.1 m. Find the perimeter of the room and the
uncertainty.
3. At the beginning of an investigation, a student determines that
the temperature of a beaker of water is 99.8 + 0.1 °C. At the end
of the investigation, the temperature is 35.5 + 0.1 °C. What is the
change in temperature?
