Answers
The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
What are CAM?CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
Hence option (C) is correct.

Explain why you usually can’t use just a single spectral line to confirm the identity of an element.
Answers
You can't usually just use a single spectrum line to confirm the identity of an element because there are cases that the emission line id not clearly defined. When the emission line is very weak compared to surrounding noise, in which case the more datapoints you have to build up confidence for the existence of a particular emission spectra, the better.

If a gas has a volume of 1.25 l at a temperature of 300 k, what will the volume change to if the container is cooled to 200k
Answers
The volume of the gas when the container is cooled from a temperature of 300 K to 200 K is 0.83 L
Charles' law
Charles' law states as follow:
V₁ / T₁ = V₂ / T₂
Where
V₁ is the initial volume T₁ is the initial temperature V₂ is the new volume T₂ is the new temperature How to determine the new volumeFrom the question given above, the following data were obtained
Initial volume (V₁) = 1.25 LInitial temperature (T₁) = 300 KNew temperature (T₂) = 200 KNew Volume (V₂) =?V₁ / T₁ = V₂ / T₂
1.25 / 300 = V₂ / 200
Cross multiply
300 × V₂ = 1.25 × 200
Divide both side by 300
V₂ = (1.25 × 200) / 300
V₂ = 0.83 L

The enthalpy change of condensation of water is negative and here the entropy change also negative and the process is nonspontaneous.
What is enthalpy change?The enthalpy change of a reaction or a phase change is the change in heat energy absorbed or evolved. The change in enthalpy is dependant on the nature of process as well on temperature of the system.
Condensation of water is the change of its liquid state into solid state. Thus water freezes to form ice. In this process, the system is getting more ordered structure in the solid state and thus, the entropy of the system decreases means the entropy change is negative.
Now, when converting liquid to solid heat is released by the system. Hence, enthalpy change, delta H is negative. A process becomes spontaneous only f its Gibbs energy is negative.
Here we have both negative entropy and enthalpy so make Gibbs energy negative higher temperature is needed.
Condensation of a substances is taking place at very low temperature and thus gibbs energy become positive. Therefore the process is nonspontaneous.
