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.
For example, the conductivity reading of a salt. solution of sodium chloride typically increases by 2% for every Centigrade degree of temperature change. Therefore, the conductivity. value of a salt solution at 15Â°C can be expected to be about 20% different than the value at 25Â°C.
