Interactions of Solar Energy

• Water (Hydrosphere)
• Capable of absorbing huge amounts of heat energy
  (becomes a heat sink a region that absorbs and
  stores heat energy)
• This is possible because water has a high
  specific heat capacity the amount of energy
  required to change 1 g of water by 1?C is
  comparatively large.

• Q mc?t

• ?t temperature change
• m mass (g)
• c specific heat capacity
• Q heat energy (J or kJ)

EX. How much energy will it take to heat 100g of
water from 20?C to 50?C?

• (Q) is the amount of heat energy that is required
  to cause a certain temperature change in a mass
  of a particular substance
• If there is a change of state occurring, no
  temperature change is happening, but vast
  quantities of energy are still involved

• Since 2/3 of Earth is covered in water, which can
  absorb heat and then release it, water acts as a
  moderator of our temperatures and drives our
  weather systems
• The absorption of solar energy is also what
  drives the water cycle
