Answer:
2. Decreases
Explanation:
From the combined concept of entropy and the second law of thermodynamics, it can be concluded that during the positive change in entropy, the degree of randomness of a system increases.
But in case of photosynthesis, we see a negative entropy change because in the process of photosynthesis plants take disordered things as from the atmosphere and water from soil and finally make a highly ordered molecule Glucose, which is further used as a food product and source of energy by the plants. Thus it is clear that degree of randomness in decreasing in the process of photosynthesis and it is a negative change in entropy.
If there is no atmosphere on the planet or the heavenly body on which we are the observers, then there would be no scattering of the sun's light and hence, the sky would aappear black. For example, if we are on the moon, the sky appears black ,unlike on earth(where it appears blue) because there is no atmosphere on moon.
The answer is 310 g LiNO3
