The drift speed of Bovine Serum Albumin (BSA) under the influence of electric field in aqueous solution was monitored at several values of pH and the speed values are listed below (opposite signs indicates opposite direction of travel). What is the isoelectric point of the protein?

During winter, the moisture condenses in the form of dew and can be seen on plant leaves and grass. The entropy of the system, in such cases, decreases as liquids possess lesser disorder as compared to gases. With reference to the second law, which of the following statements is correct for the above process?
