There are many causes of chest pain. One is angina which results from inadequate oxygen supply to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. Chest pain can also be due to a heart attack (coronary occlusion) and other important diseases.
Conclusions We have demonstrated here the significant effect of temperature on the conductivity measurements of solutions. This highlights the importance of maintaining standard and test solutions close to the reference temperature when taking measurements in order to obtain the most accurate conductivity values.
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m).esistivity of pure water (in MÏ-cm) as a function of temperature. The SI unit of conductivity is S /m and, unless otherwise qualified, it refers to 25 Â°C. Often encountered in industry is the traditional unit of Î¼S/cm. 10 6 Î¼S/cm = 10 3 mS/cm = 1 S/cm.
