NH3. Ammonia is composed of one nitrogen atom, and three hydrogens.
Answer : The correct option is, (2) gas to liquid
Explanation :
Entropy : It is defined as the measurement of randomness or disorderedness in a system.
The order of entropy will be,
As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.
As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.
In option 1, 3 and 4, the entropy increases. while in option 2, the entropy decreases.
Hence, the correct option is, (2) gas to liquid
It should be mass and speed so they are both incorrect because the height doesn’t mean much, but what matters is how heavy the object is, and how fast it’s going to go.
The chromosphere is the third and the lowermost layer of the sun and appears bright red. This chromosphere region is visible only during the total solar eclipse. Thus, option B is correct.
<h3>What is a solar eclipse?</h3>
A total solar eclipse is an event in which the new moon is in between the Earth and the Sun resulting in the formation of the dark shadow on the Earth's surface.
During this eclipse, the chromosphere region of the sun is visible as it was hidden by the photosphere before the eclipse. It shines bright red and yellow as the spectral line of the hydrogen alpha is emitted.
Therefore, option B. the chromosphere region is visible only during the total solar eclipse.
