1. 1. A learner reads a laboratory thermometer while looking down at the meniscus from above. What kind of error does this cause, and how does it affect the reading?

   • A. Parallax error; the reading is too high
   • B. Parallax error; the reading is too low
   • C. Calibration error; the reading is too high
   • D. Zero error; the reading is too low

2. 2. During an experiment, a learner measures the temperature of warm water as 45 °C. What is this temperature in kelvin?

   Type your answer (in K) in the lesson.

3. 3. Why can an alcohol-in-glass thermometer NOT be used to measure the temperature of boiling water?

   • A. Alcohol freezes at 0 °C
   • B. Alcohol boils at 78 °C, which is below 100 °C
   • C. Alcohol does not expand when heated
   • D. Alcohol is silvery and opaque

4. 4. Which is the correct way to place a laboratory thermometer when measuring the temperature of water in a beaker?

   • A. Rest the bulb on the bottom of the beaker
   • B. Press the bulb against the side of the beaker
   • C. Keep the whole bulb in the liquid without touching the bottom or sides
   • D. Remove it from the water before reading so it is easier to see

5. 5. What name is given to the curved upper surface of a liquid column inside a thermometer's narrow tube?
