Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of subst

ance A is 6.27 g and its initial temperature is 20.9 ∘C . The mass of substance B is 26.1 g and its initial temperature is 52.7 ∘C. The final temperature of both substances at thermal equilibrium is 46.3 ∘C.
If the specific heat capacity of substance B is 1.17 J/(g⋅∘C), what is the specific heat capacity of substance A?

Think about the animals in an arctic ecosystem. How would those animals adapt over time if global temperatures rise over the nex
brilliants [131]

Given the fact that we are seeing a rise in the temperature of the globe, the artic animals in that ecosystem must adapt by a reduction in the rate of metabolism.

<h3>What is global warming?</h3>

Several evidences continue to emerge that the temperature of the earth have continued to increase and this is largely due to the fact that since the turn of the twentieth century and the rise of industrialization, there have been a rise in the emission of the carbon dioxide and other green house gases into the environment. As a result of this, the temperature of the earth has continued to rise steadily leading to the melting of the ice cover and the destruction of ecosystems that are found around the artic regions of the earth.

Now, we know that an organism is able to adapt to the changes that occur in its habitat by being able to alter some of its structure and function.

Given that the organisms that live in the artic are adapted to cold regions and low temperatures, the metabolic rate of the organisms is high in order to produce heat.

As a result of the rise in global temperatures, the organisms would have to reduce their rate of metabolism.

mote1985 [20]
Similarities:
they both made sediment into soil
they both form the earth
they both made sediments have cracks

differences:
physical is reliant usually on contact with atmospheric condition

chemical transforms rocks into sediments while physical only breaks it down

chemical uses chemical reactions
