Answer: Option (a) is the correct answer.

Explanation:

When water is boiled then due to the heat provided vibration between the particles increases. As a result, there will be increase in kinetic energy of particles.

Hence, vibration between the particles of boiling water will be the fastest.

Whereas vibration of particles in frozen water, room temperature water and cold tap water will not be the fastest.

Answer:

$\large \boxed{\text{2.5 L}}$

Explanation:

1. Calculate the moles of NaOH.

$\text{Moles} = \text{20 g} \times \dfrac{\text{1 mol}}{\text{40 g}} = \text{0.50 mol}$

2. Calculate the volume of NaOH

$\begin{array}{rcl}\\\text{Molar concentration} &= &\dfrac{\text{moles}}{\text{litres}}\\\\ n &= &\dfrac{c}{V}\\\\\dfrac{\text{0.2 mol}}{\text{1 L}} &=& \dfrac{\text{0.50 mol}}{V}\\\\ \dfrac{0.2V}{\text{1 L}} & = & 0.50\\\\0.2V &= & \text{0.50 L}\\V & = & \dfrac{\text{0.50 L}}{0.2}\\\\& = & \textbf{2.5 L}\\\end{array}\\\text{The volume of the solution is $\large \boxed{\textbf{2.5 L}}$}$

Fill in the sentences below to explore the process by which a storm becomes a hurricane. some terms may be used more than once.

Reptile [31]

Answer:

The sentences which are made by the given sentences are as :

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.

Explanation:

Here in the question it has been mentioned to form the sentences with the given one:

Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
A tropical disturbance leads to an array of clouds which are disorganized also there are thunderstorms with no rotation or little rotation with it.
When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
When the storm reaches a tropical storm stage it gets its name.
All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.

These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
