<span>An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. Thus, its components include plants, animals, and microorganisms; soil, rocks, and minerals; as well as surrounding water sources and the local atmosphere. The size of ecosystems varies tremendously. An ecosystem could be an entire rain forest, covering a geographical area larger than many nations, or it could be a puddle or a backyard garden. Even the body of an animal could be considered an ecosystem, since it is home to numerous microorganisms. On a much larger scale, the history of various human societies provides an instructive illustration as to the ways that ecosystems have influenced civilizations.

1.What is the specific heat capacity of granite when 20 kg absorbs 237 000 J of heat energy, causing its temperature to increase
Natalka [10]

<u>Given</u> :

  • Amount = 20 kg
  • Heat energy absorbed = 237,000 J
  • Temperature change = 15 °C

<u>Formula applied</u> :

\boxed {Q = mc \triangle T}

  • Q = absorbed heat
  • m = mass
  • c = specific heat capacity
  • ΔT = temperature change

Let's solve for c !

⇒ 237,000 = 20 × c × 15

⇒ c = 237,000 ÷ 300

⇒ \boxed {c = 790 J kg^{-1} K^{-1}}

∴ The specific heat capacity of granite is <u>790 J kg⁻¹ K⁻¹</u>.
