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.

Answer:
because velocity is a vector quantity and has direction associated with it
Explanation:
Answer:
2.00 × 10⁻³ g
Explanation:
Step 1: Write the balanced decomposition reaction
2 NaHCO₃ ⇒ Na₂CO₃ + CO₂ + H₂O
Step 2: Calculate the moles corresponding to 0.0118 g of Na₂CO₃
The molar mass of Na₂CO₃ is 105.99 g/mol.
0.0118 g × 1 mol/105.99 g = 1.11 × 10⁻⁴ mol
Step 3: Calculate the moles of H₂O produced with 1.11 × 10⁻⁴ moles of Na₂CO₃
The molar ratio of Na₂CO₃ to H₂O is 1:1. The moles of H₂O produced are 1/1 × 1.11 × 10⁻⁴ mol = 1.11 × 10⁻⁴ mol.
Step 4: Calculate the mass corresponding to 1.11 × 10⁻⁴ moles of H₂O
The molar mass of H₂O is 18.02 g/mol.
1.11 × 10⁻⁴ mol × 18.02 g/mol = 2.00 × 10⁻³ g
Nitrogen, for example, is a gas that liquefies at about −200° C and freezes around −210° C, whereas bismuth is a solid melting at 271° C and boiling at about 1,560° C.
