The answer is
kangaroo rat is adapted to living in an environment where water is scarce.
The student is incorrect. Although the amount of copper sulfate dissolved has increased in the new solution, we also have to account for the fact that the amount of water has also increased.
To see whether or not the new solution is more concentrated, we can compare the grams of copper sulfate in each solution to the amount of water in each solution.
Solution A:
Solution B:
Solution A + Solution B:
You'll notice that the concentration for all these solutions is .1 g copper sulfate/1mL
This means that the new solution (A+B) is not more concentrated -- the increase of dissolved copper sulfate was diluted by the additional increase of water, such that the concentration of the new solution was not greater than its component solutions (A and B).
Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Hence, Option (D) will be the correct option
<h3>What is Heat radiation ?</h3>
Heat Radiation refers to the transfer of heat from a hot body to cold body directly, without heating the medium between two bodies.
Vaccum does not have any particles in it. Thus, there will be no transfer of heat through it.
The best example of it is thermous flask in which vaccuum inside thermous flask reduces the transfer of energy through it.
Hence,Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Thus, Option (D) will be the correct option
