<h2>Answer : Option D) Heterogeneous mixture</h2><h3>Explanation : </h3>
A mixture in which particles are not evenly distributed and particles keep their unique properties are called as heterogeneous mixture.
Usually, in heterogeneous mixture the substances are not evenly distributed and they can be easily separated through any physical methods. Also the components retains their original/unique properties in the mixture. It usually contains various particles from different substances that are not uniformly distributed throughout the mixture.
Explanation:
While atomic radii DECREASE across a Period, a row of the Period Table, from left to right as we face the Table, atomic radii INCREASE down a Group, a column of the Periodic Table, due to the shielding of the valence electrons by the closed valence shell(s) that intervenes between the nucleus and the valence, outermost electrons.
Answer:
Waterwould be the best choice
Explanation:
<em>The specific heat capacity</em> refers to how much energy is required to raise the temperature of an object. The higher the specific heat capacity, the more energy is required to heat a given substance. This would also mean that w<u>ith a higher specific heat capacity, a substance would be able to retain more heat</u>.
With the above statements in mind, water would be the best choice, because it would retain more heat than the other substances once it reaches 100 °C, and in turn water would emit the most heat while it cools.
