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.
What is the percentage variation of the resistivity of copper over the temperature range from room temperature (20 degrees Celsius) to 116 degrees? Part B:Assume that a copper wire's resistance changes due to only resistivity changes over this temperature range.
