Answer

Brief Explanations:

  • The SI unit of temperature is the Kelvin, but Celsius is also widely - used in scientific and everyday contexts, and water boils at 100°C under standard atmospheric pressure.
  • A dime is about 1 mm thick, not 1 g thick (g is a unit of mass).
  • A carton of milk can hold around 1.89 L, which is a reasonable volume measurement.
  • A teaspoon of medicine is about 5 mL, not 5 cm (cm is a unit of length).
  • A football field is about 91 m long, which is a correct length measurement.
  • Mass per unit volume (5 g/cm³) is a density measurement, but the description of the mass of a paper - clip as a density is incorrect.

Answer:

  • Water boils at 100°C.
  • A carton holds 1.89 L of milk.
  • A football field is about 91 m long.
