According to the graph, we can see that the white cans cool a little bit slower than black cans on the same conditions.
On the first ten minutes, we can see that the temperature of water in black cans decreased from 100°C to 50°C. and the temperature of water in white cans decreased from 100°C to 75°C.
To explain this, you need to know what is a dark and white color?
<span>it's a color in which the total absorption of all wavelengths and none of these wavelengths will be reflected. But since light is a form of energy expression, </span>we can conclude that the black color has no energy on it. on the opposite of the white color, which absorbs all wavelengths, so it has energy on it (which will turn into heat), and that's why it could keep the temperature better than the dark color (all is about energy).
Answer:
<h3>The plastic cube if released in water does not sink and rather floats on the surface. This called the phenomenon of buoyancy. Plastic is water repellent object and it has high rates of buoyancy, when compared to other objects. As plastic is lighter than the water it tends to float on the surface. </h3>
The correct answer is vestigial.
A vestigial composition is an anatomical characteristic, which no longer appears to exhibit an objective in the present form of an organism of the given species. Usually, these vestigial compositions were organs, which had done some essential activity in the organism at one time in the past.
The examples of human vestigiality are plentiful, involving the anatomical compositions like wisdom teeth, human tailbone, and inside corner of the eye.
Answer:
Below:
Explanation:
Minerals. Needed for synthesizing plant components e.g. calcium, magnesium, nitrates, phosphates and potassium ions. They enter root hairs, dissolved in water, by active transport and are transported by xylem.
