A group goes vertically and a period goes horizontally.
(a group goes down and a period goes across)
Answer: Option (d) is the correct answer.
Explanation:
In water cycle, water from clouds fall in the form of rain, snow etc. This water travels through the surface of mountains and passes through rivers, oceans etc and gets evaporated due to heat from Sun.
When water evaporates then it absorbs energy in the form of heat from Sun and when water condenses then heat is released.
Therefore, water gains energy during evaporation and releases it during condensation.
I would say the head and heart because if you swim deep in the ocean you will feel pressure in your heart and head because the muscles in your body are closing in on them

For example...
You have solution with [H+] = 0,01M
>>>> pH = -log[H+] = -log0,01 = 2
And you increase the [H+] by 10x ---> 0,01×10 = 0,1M
>>>> pH = -log0,1 = 1
○ pH decrease by 2x
○ pH is more acidic
