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.
Certain factors can affect how well a material conducts electricity. 1  Temperature - Changing temperature of silver or any other conductor alters its conductivity. In general, increasing the temperature causes thermal excitation of the atoms and decreases conductivity (increases resistivity).
