This question includes four answer choices:
A. definite volume, highest molecular motion, highest kinetic energy
B. indefinite volume, least molecular motion, highest kinetic energy
C. definite volume, least molecular motion, lowest kinetic energy
D. definite volume, no molecular motion, lowest kinetic energy
Solids do not have the highest molecular motion (on the contrary they have the least molecular motion), so you can discard option A. Solids have a definite volume and the highest kinetic energy (given that they have the least molecular motion), so you discard option C. Molecules always have a vibrational motion, so you discard option D. Option C, have only characteristics that correctly describes a solid: definite volume, least molecular motion, lowest kinetic energy. Therefore, the answer is the option C.

The solubility of a gas (Sgas) is directly proportional to its partial pressure (Pgas). what pressure of carbon-dioxide is required to keep the carbon dioxide concentration in a bottle of club soda at 0.12 M at 25 degrees Celsius ? 0.12 M = 3.4 x 10^-2 (Pgas?)
Answer: 
< 0
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
For the reaction 
In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus is negative or less than zero.
