Answer:
<em><u>Step by step explanation</u></em><em><u>:</u></em>
<em>Given:</em>
Mass of given sample (m) = 2.50 g
Initial temperature (T1) = 25°C
Final temperature (T2) = 20°C
Heat Energy Q = 12 cal
<em>T</em><em>o </em><em>find:</em>
<em></em>
<em>Solution</em><em>:</em>
We know that,
<em>Specific</em><em> </em><em>heat</em> <em>of </em><em>any </em><em>substance </em><em>is </em><em>directly</em><em> </em><em>proportional</em><em> </em><em>to </em><em>the </em><em>mass </em><em>and </em><em>change </em><em>in </em><em>temperature.</em>
Represented by equation,
Where,
<em>Q = Heat Energy</em>
<em>m = mass of given sampl</em><em>e</em>
<em>c = specific heat</em>
<em>∆T = change in </em><em>temperature</em>
Substituting corresponding values,
<em></em>
We also know that,
multiplying above answer by 4.184,

Answer:
Limestone is a pure substance
Explanation:
It includes many elements and compounds that make it more difficult to break down Limestone.
The fluctuations in abiotic cycles can influence the population in many ways. The population of a particular area depends on the various abiotic cycles such as nitrogen cycle, carbon cycle, phosphorous cycle. The changes in these cycles affects the life of population. Fluctuation results in hibernation of species. Some of the organisms migrate to another place in search of normal environment. The early breeding results in creating problems. It disturbs the ecological balance by using the limited supply of resources. The fluctuation in phosphorous cycle can affect the aquatic population. As the dependency of population on abiotic cycles is as important as the biotic factors the fluctuations can cause many problem.
