Answer : The correct option is, (D) 6.022\times 10^{23}

Explanation :

Scientific notation : It is defined as the way or representation of expressing the number that are too big or too small that is written in the decimal form. That means always written in the power of 10 form.

For example : 700 is written as, 7\times 10^2

As we are given that the value of Avogadro’s number is, 602,200,000,000,000,000,000,000

This number is written in scientific notation as :

6.022\times 10^{23}

Therefore, the correct option is, (D) 6.022\times 10^{23}

Describe in your own words, in terms of particle movement and energy, what occurs when a liquid is cooled to its freezing point.
IRINA_888 [86]
Liquids have free and fast moving particles. Liquids do not take a specific shape unless they are enclosed such as in a bottle. Anyway, since they are free flowing when they freeze, their movement becomes very slow. Eventually the particles will not have room to move as they used to and will be held in one place. The particles are still moving but they are only shaking or vibrating in the same place. You can't even tell this movement is happening, and that is what happens when liquid freezes.
