Question

the unit symbols km, kg, and kl are symbols for what prefix?
a kelvin
b cent
c kilo
d none of the above

Explanation:

• Kelvin (A): Kelvin is a unit of temperature, not a prefix.
• Cent (B): The prefix "cent" means one - hundredth (e.g., centimeter, \(1\ cm=\frac{1}{100}\ m\)). But \(km = 1000\ m\), \(kg=1000\ g\), \(kl = 1000\ l\).
• Kilo (C): The prefix "kilo" means \(10^{3}\) or 1000. For example, \(1\ km = 1000\ m\), \(1\ kg=1000\ g\), \(1\ kl = 1000\ l\).

Answer:

C. Kilo
