4. una cucharadita de syrup tienen un volumen de 5 ______

las estadísticas muestran que fumar un cigarro disminuye la expectativa de vida 642000 -------- o 10.7 minutos.
parte c: metric conversion factors
1l = 1000 ml 1m = 100cm 1dm = 10cm

Explanation:

Step1: Identify unit types

• $\text{cm}^2$ is area as it measures the extent of a two - dimensional surface.
• $\text{s}$ is time as it measures the duration.
• $\text{km}$ is length as it measures distance.
• $\text{g}$ is mass as it measures the amount of matter.
• $\text{cm}^3$ is volume as it measures the amount of space occupied.
• $\text{mm}$ is length as it measures distance.
• $\text{mg}$ is mass as it is a smaller unit of mass.
• $\text{L}$ is volume as it is a unit for measuring liquid or gas volume.
• "gr kelvin" (should be "K" for Kelvin) is temperature as it measures hotness or coldness.

Step2: Fill in appropriate SI base units

• The SI unit of length is the meter (m).
• The SI unit of mass is the kilogram (kg).
• The SI unit of volume for the metric system can be the liter (L) or cubic - meter ($\text{m}^3$), but the base SI unit for volume in terms of length is $\text{m}^3$.

Step3: Answer Part B

• Soda is usually bought in liters (L), so the unit for soda volume is L.
• The mass of a bowling ball is typically in kilograms (kg), so 7.25 kg.
• The mass of a paper - clip is about 1.0 gram (g).
• A teaspoon of syrup has a volume of 5 milliliters (mL).
• To convert 10.7 minutes to seconds, since 1 minute = 60 seconds, then 10.7 minutes = 10.7×60 = 642 seconds. So the unit for the time reduction in life - expectancy is s.
