One way is measuring fluid output. However, concentration and contents are as important. It was this activity’s aim to determine changes in nappy weight, based not just on the amount but also on the concentration and…

In addition, infants have still to develop a urinary system that concentrates or dilutes urine in response to changes in extracellular fluid. Aside from that, they are still unable to effectively communicate their complaints, It is thus important that an outside monitoring of water loss and input be conducted to prevent complications such as dehydration or edema (Ambalavanan, 2010).
Early determination of abnormal fluid levels gives room in early intervention and prevention of complications. Usually, one can predict predilection of infants to abnormal fluid levels by the maternal and newborn history. As well, measuring of fluid output through urine, stool, nasogastric, orogastric, and cerebrospinal fluid may be conducted (Ambalavanan, 2010).
For this experiment, four nappies per pair were prepared. After previously weighing all four, two (labelled 1 and 2) were added with 15-50 ml water, while the remaining were added with 15-50 l of concentrated salt. Weight differences between unused and wet nappies were then determined and presented in the tables below.
Table 1 summarizes the data collected by the pair of experimenters. As can be seen, the differences among the unused nappy weights were minimal, with the mean weight at 10.2 ± 0.2 grams. Any detected differences among wet nappies, must thus be because of the fluids they contain, and not of the material they are made of.
Looking at the data of other pairs (table 2), specifically of group 2, it can be seen that equal volumes of water and salt solution does not cause any significant differences in the change of nappy weight. In support of this data, group 3 found that pouring a volume of the salt solution that was twice as much as the volume of water caused almost twice as high weight difference as that recorded in nappies added with the same amount of water.
Data gathered by this pair of experimenters, as well as of other groups were not used in

The accomplishments of the project were in enabling the robotic arm to move through a space within set constraints of avoiding the black lines in the experiment. The software for the robotic arm is executed by the machine to achieve the objectives of the project.
The parabolic movement is the path traced by an object vertically, with constant acceleration, while the movement horizontally is at a constant velocity. The initial velocity and the projection angle determine
For the first cycle, the mass of the water alone is the mass of the crucible lid and hydrate, less the mass of the crucible lid and residue after heating. That gives 22.678 – 22.460 = 0.218. The mass of the hydrated salt is the mass of the crucible lid and hydrated salt, less
For this experiment a cuvette, calorimeter, and a color of your choice for the dye solution, A.To begin the experiment, clean the cuvette. Wash out the cuvette three times with water, and then three times with solution. Once
