All life depends on capturing energy from the sun and converting it in to a form that living organisms can use.
- Two key processes (mirror each other)
- Photosynthesis (Sun -> Plants)

The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
<em>expand the equation;</em>
x² - 40x + 400 = x² - 20
<em>collect similar terms together;</em>
x² - x² - 40x = -20 - 400
-40x = -420
Thus, the value of the unknown number is 10.5.

Answer:
A) Ice cream starts dripping down the sides of an ice cream cone: melting
B) Fog is created by using dry ice: sublimation
C) Frost forms on trees on a very cold day: deposition
D) The mirror gets fogged up when you breathe on it: condensation
E) Your wet hair dries after a few minutes: evaporation
F) Liquid glass cools and hardens : freezing
Explanation:
Sublimation process where solid state changes to gaseous state by escaping liquid state.
Deposition process where gaseous state changes to solid state by escaping liquid state.
Condensation process where gaseous state changes to liquid state.
Melting is the process where solid state changes to liquid state.
Evaporation process is a process where liquid state changes to gaseous state.
Freezing is the process in which liquid changes to solid state.
