5: SMALL VOLUMES L. It takes about 20 drops of liquid to make 1 milliliter. There are 1000 milliliters in one liter. How many drops would it take to fill the 2-liter bottle in Image #5? M. What is the difference between a milliliter and a millimeter? STATION 5 2] 6: TEMPERATURE MEASUREMENT Normal human body temperature measures 98.6 degrees F. The \"F\" stands for \"Fahrenheit\". On the Fahrenheit temperature scale, 32 degrees is the temperature at which water freezes, and 212 degrees is the temperature at which water boils. In the metric system, temperature is measured using a different scale, called the Celsius scale. You have probably seen temperatures reported in both Fahrenheit and Celsius degrees on TV weather reports. In the Celsius system, the freezing point is 0 degrees, and the boiling point is 100 degrees. N. Look at the Celsius thermometer seen in Image #6. What is the temperature reading in degrees Celsius? 0 C O. What happens to water when it reaches zero degress Cellsius? P. What happens at 100 degrees Celsius?
