A solid is characterized by structural rigidity and resistance to a force applied to the surface a solid object does not flow to take on the shape of its container nor does it expand to fill the entire available volume like I gas
The substance has a higher density than water
Answer:
Action given and reaction taken
Also known as
Newton's third law of motion
Explanation:
An action will be done such as bouncing a ball on the wall
- You throw the ball (Action)
- The ball bounces back (Reaction)

Answer:
The correct answer is B. It is spontaneous only at low temperatures.
Explanation:
In thermodynamics, the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.
The spontaneity of a reaction is given by the equation:
ΔG = ΔH - TΔS
where:
ΔH: enthalpy variation
T: absolute temperature
ΔS: entropy variation
As the reaction is exothermic, ΔH<0
As the reaction order increases (the reagents are solid and gas and their product is solid), ΔS<0
Therefore, the reaction will be spontaneous when ΔG is negative.
ΔG = ΔH - TΔS
That is, the entropy term must be smaller than the enthalpy term.
Hence, the reaction will be spontaneous only at low temperatures.
