What do you understand by temperature independence paramagnetism?Ans) Compounds which are expected to be diamagnetic may exhibit this kind of weak paramagnetism. It arises from a second-order Zeeman effect in which additional splitting, proportional to the square of the field strength, occurs. It is difficult to observe as the compound inevitably also interacts with the magnetic field in the diamagnetic sense. Nevertheless, data are available for the permanganate ion.[13] It is easier to observe in compounds of the heavier elements, such as uranyl compounds.

Q. Determine the heat transfer? Ans. Let's say a blacksmith tosses a hot horse shoe into a bucket of water. The horseshoe will get cooler while the water gets hotter. Ideally
Trace and ultratrace analysis: The accuracy, precision and detection limits of flame AAS depend on how the analyte sample is introduced into the atomiser. We need to transfer
Atomic emission spectrometry: In atomic emission spectrometry (AES), a reproducible and representative amount of the sample is introduced into an atomization-excitation source
