is the probable answer, which I don't know how to explain, but I know that's the answer because I learned about it a few years ago and I'm pretty smart. =]

<u>Answer:</u> The given statement is true.
<u>Explanation:</u>
For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.
The equation used to calculate Gibbs free energy follows:
Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change 
of the reaction comes out to be negative for this kind of reaction.
Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as 
. Randomness of gaseous particles is more than that of liquid which is further more than that of solids.
We are given:
A solid substance is converting into a gaseous substance.
As, the entropy is increasing. So, the entropy change is positive.
Thus, the above reaction is spontaneous.
Hence, the given statement is true.
Answer: humans would find more efficient ways of growing crops
Explanation:
The molar amount of gas can most likely be found by using the ideal gas law. This is because the ideal gas law states pV = nRT. P, V, and T are the pressure, volume, and temperature, which are the known variables. The R stands for the Universal Constant of Gases; also known. Therefore, the unknown is n, the number of moles (molar amount) of gas, and so you would solve for n from the law.
Answer: A) The molar amount of gas
