I think I it’s gonna be C.
Answer:
<u>The temperature difference is</u> ![\frac{300}{m} Kkg^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B300%7D%7Bm%7D%20Kkg%5E%7B-1%7D)
Explanation:
The formula that is to used is :
Δ
Δ![T](https://tex.z-dn.net/?f=T)
<em>where ,</em>
- <em>Δ
is the heat supplied in calories = 300cal</em> - <em>
is the mass of water taken = m (assumed)</em> - <em>Δ
is the change in temperature</em> - <em>
is the specific heat of water =
</em>
ΔT :
![\frac{300}{m*1} \\=\frac{300}{m} Kkg^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B300%7D%7Bm%2A1%7D%20%5C%5C%3D%5Cfrac%7B300%7D%7Bm%7D%20Kkg%5E%7B-1%7D)
<span>This example represents the challenge of survival of the fittest. In this situation, the trees have a distinct advantage due to their above average height. This puts them in the best position to gain the resources that they need to survive, most notably, the sun. The smaller plants, however, do not have this advantage, and lose out to the trees.</span>
