Answer:
The water cycle consists of 3 major processes.
**Evaporation
**Condensation.
**Precipitation.
01)Evaporation, : Evaporation is the process of a liquid s surface changing into a gas.
02)Condensation: Condensation is the process of gas changing to a liquid.
03)Precipitation: In the water cycle, water vapour in the atmosphere condenses and become liquid.
WHAT IS WATER CYCLE DO?
## The water cycle shows the continues movement of water within the Earth and atmosphere.
** Liquid Water--------------- Water vapour. ( Evaporate)
*** Condenses-------- To Clouds
( Turn)
, and precipitations back to the form of rain and snow. Water do transform around the atmosphere.
Tip::: who made the water cycle???
The sun heat.

When The rate of effusion is inversely proportional to the √molar mass of the substance.
and we have R(He) = 1L / 4.5 min so,
R(He)/R(Cl2) = (molar mass of Cl2/ molar mass of He)^0.5
and when we have the molar mass of Cl2 = 70.9 & the molar mass of He = 4
so by substitution:
(1L/4.5 min)/ R(Cl2) = (70.9 / 4)^0.5
(1L/4.5 min) / R(Cl2) = 4.21
∴R(Cl2) = (1L/4.5 min) / 4.21 = 1L/ (4.5*4.21)min = 1 L / 18.945 min
∴Cl2 will take 18.945 min for 1 L to effuse under identical conditions
