Effects of Chlorides on Corrosion of Simulated Reinforced

Since there is limited dissolution of oxygen in the pit solution, the cathodic reduction of dissolved oxygen on the metal surface adjacent to the pit sustains the pit growth. The cathodic site, the metal surface, is very large compared to the pit size, and this makes the pit grow at a fast and an ever increasing rate .

Development of the technique for determination the rate of

In particular, it is known that the process of dissolution of lead oxides is characterized by the determining effect of the oxygen transport diffusion stage in a liquid metal. This means that the hydrodynamic conditions for a liquid metal flowing around oxides significantly affect the dissolution rate.

Temperature Effects on Solubility Galileo

Some substances are insoluble in water, but many more substances are soluble in water to some degree. The solubility of a substance in water depends on several factors. One of the most important factors is temperature. This activity is written to use any salt to finding the temperature dependence of solubility.

What's the Relationship Between VO2max and Heart Rate

There is a positive correlation between heart rate and oxygen consumption—the closer you are to your maximal heart rate, the closer you are to your VO2max. So when you are doing interval training, you are going at (near) maximum heart rate and (near) maximum VO2max during the high intensity intervals.
