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.
The thermal conductivity of a material is a quantitative measure of how much heat will flow through a material per unit time for a given temperature gradient. In the simplest materials the mechanism of heat transfer may be described at the microscopic level as transfer of energy through collisions between atoms and molecules. In a higher temperature region region the atoms and molecules have more kinetic energy than in a low temperature region.
