Fig. 3 shows the temperatures of magnesium, calcium, strontium, and barium chloride solutions that were exposed to 2.45 GHz microwaves for 40 s. A similar effect that is less temperature in the case of larger VTP-27999 was observed. Under similar conditions, one molar solution of magnesium chloride has the temperature of 36.9 °C while barium chloride has 31.7 °C. Barium being smaller than cesium has the high temperature in comparison to that of the latter. Thus, the size of ion is more prominent to fix water molecules around them in comparison to charge. For example, lesser size of magnesium, calcium, strontium, and barium in comparison to the corresponding members of group IA induces more temperature in their solutions despite the fact that they have double charge. To further confirm the results, a set of three ions (cobalt, copper, and nickel) having almost the same size and charge were studied (Fig. 4) and aggregates was found that as there was no significant difference between the charge and size, the temperatures were almost similar in each case.
