Question

13 ordering 1 point order the following prefixes smallest to largest. smallest 1 micro- 2 kilo- 3 centi- 4 nano- 5 milli- largest 14 multiple choice 1 point what happens to particles in matter when thermal energy is absorbed? the average speed of the particles increases.

Explanation:

Step1: Recall prefix - value relationships

Nano - represents $10^{-9}$, micro - represents $10^{- 6}$, milli - represents $10^{-3}$, centi - represents $10^{-2}$, kilo - represents $10^{3}$.

Step2: Order the prefixes

Based on the above values, the order from smallest to largest is nano -, micro -, milli -, centi -, kilo -.

for question 14:
When thermal energy is absorbed by matter, the kinetic energy of the particles increases. Since kinetic energy is related to the speed of particles ($KE=\frac{1}{2}mv^{2}$), the average speed of the particles increases.

Answer:

1. Nano-
2. Micro-
3. Milli-
4. Centi-
5. Kilo-
