Answer:
The answer to your question is below
Explanation:
Atomic mass = 65.39 g
Searching this number in the periodic table we find that the element is Zinc.
Then:
# of Protons = 30
# of neutrons = atomic mass - # of protons
= 65.39 - 30
= 35.39
# of electrons = # of protons = 30
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.
