Answer: Picture (d) is the correct answer.
Explanation:
When liquid nitrogen is at -320 degrees then as the temperature is very low, therefore, molecules of nitrogen will be much closer to each other.
Whereas when liquid nitrogen is boiled then we are increasing the temperature. As a result, force of attraction between the molecules decreases and they will move far apart from each other.
It is known that below 63 K liquid nitrogen tends to freeze and thus it becomes solid. So, at -320 degrees liquid nitrogen will be in solid state.
In the given pictures, picture (d) represents the change caused by adding heat to liquid nitrogen.
Yes, they both cast shadows. A eclipse occurs when one enters the shadow of the other.
Solar eclipse: Earth in shadow of Moon.
Lunar eclipse: Moon in shadow of Earth.
A solar eclipse is the result of one celestial body being completely or partially obscured by another celestial body along the line of sight of an observer. A solar eclipse occurs when the moon passes between the earth and the sun, obscuring all or part of the sun's disk. A lunar eclipse occurs when the Moon passes through the Earth's shadow, making the Moon's surface completely or partially obscured.

By counting the protons in the element
Answer:Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.
