Interpretation:
The trend to the relationship between gas solubility and temperature have to be described.
Concept introduction:
Solubility can be defined as maximum amount of solute that can dissolve in known amount of solvent at a given temperature and pressure.
With increasing the temperature, the solubility of a gas in liquid decreases.
Answer to Problem 129A
From the data, the solubility of oxygen gas in surface ocean waters increases as latitude increases towards both north and south as the temperatures of surface water decreases toward the poles. Near the equator, the solubility of a gas in liquid is lowest. The temperatures of surface water are highest near the equator and the solubility of oxygen decreases.
Explanation of Solution
From the data, the solubility of oxygen gas in surface ocean waters increases as latitude increases towards both north and south as the temperatures of surface water decreases toward the poles. Near the equator, the solubility of a gas in liquid is lowest. The temperatures of surface water are highest near the equator. At higher temperatures, the escaping tendency of the gaseous particle from the solution increases results in the solubility of oxygen gas decreases.

Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt.

Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away).
