Salt Water Hydration Lab Report

743 Words3 Pages

These results were worthwhile as it can be useful to assist high-intensity endurance athletes to maintain peak performance through hydration. In these events, liquids are not readily available so it is useful to know which liquid evaporates the slowest so that they can get the most out of a liquid, and hence the hydration out of that given drink, in this case, it is Salt Water. It's also useful to assist people when exploring deserts or hot countries like Australia. In hot climates, liquids evaporate faster as more energy is present. This experiment is useful for tourists, so that they know to stay hydrated and make sure they are always covered in any situation in the areas of hydration.

If the experiment was carried out using these brief measurements, it could have resulted in marginally different results. It could've affected the average number of milliliters evaporated in a 24-hour period for each liquid. However, this was helped by using a smaller 100mL measuring cylinder when needed to create more complex, accurate and detailed measurement, to get the proper number of averaged milliliters evaporated. This measuring cylinder also eliminated part of the human eye problem, as humans can interpret measurements differently from specific angles, this was also helped by putting my chin on the same desk so that the same angle is achieved and measuring from the bottom of the ellipse, which in turn improved the accuracy of the measurements. Another factor that affected the experiment and reliability, is that part of each liquid stuck and stayed in the divots in the disposable cups (as seen in the result photos), this was partly fixed through, shaking and hitting each disposable cup with the liquid whilst pouring it into the measuring cylinder. This didn't really work and resulted in each liquid having less liquid left, affecting the average milliliters evaporated over a 24-hour time period in the long run. It can be seen that the experiment was pretty valid as not much when wrong in the experiment, however, its validity could have been improved by eliminating certain aspects of the surrounding environment and human characteristics, e.g

Sodium Chloride Lab

Besides the inaccuracy in determining the freezing point and problems in the enthalpy of dissolution, the largest source of error was the temperature probe. Over the course of the multiple trials, the temperature probe would read somewhat inconsistent values. Due to this uncertainty, trials were performed on pure deionized water to see how far the probe read from zero degrees Celsius. Another source of error was in the calorimeter. Using two foam cups as a calorimeter is sufficient, although far from perfect.

Each group is given three thermometers either alcohol or mercury thermometer of different brands. A GPS device to determine the accurate area and elevation area of the experiment. Three thermometers were given to each group one thermometer to determine the area’s temperature and the two other thermometers are used to determine the relative humidity of the area. In determining the temperature hold the thermometer above your head for three minutes and then read the result, allow the thermometer to stand for about two minutes before getting the next reading. Due to the unavailability of the sling psychrometer regular thermometers were used in determining the relative humidity.

Tested Vapor Pressure, Viscosity, And Surface Tensions

447 Words | 2 Pages

The experiment tested vapor pressure, viscosity, and surface tension. The vapor pressure was tested by putting a drop of the liquid on the laminated paper and waiting 30 second to see which one had reverberated. The viscosity was tested by putting a drops of different liquids on the laminated paper and holding the paper vertically to see which one fell the fastest. The surface tension was tested by how far the liquid spread when a drop of it was put on the laminated paper.

For trails 1 and 2 the percent by mass of volatile water in hydrated salt came out to be 57.4% and 43.2%. This resulted in the average percent of H2O in hydrated salt is 50.3%. Introduction: The Main Purpose of this experiment was to determine the percent by mass of water in the hydrated salt. The second purpose was to

Evaporation Experiment

In this experiment the scientist will be testing different liquids to see if all liquids evaporate at the same rate. The scientist will have water, orange juice, nail polish remover, Coke, a small cooking pot, and a stove. The scientist will boil all of the liquids and measure which liquids evaporated the fastest. The science behind evaporation is when all of the molecules are rapidly in motion. Liquids evaporate due to heat, which makes the molecules in a liquid to move faster.

The Dachau Hypothermia Experiments

In modern scientific terms, the experiment would be deemed a failure. When looking back at the data, one is unable to verify its credibility. The results of an experiment are supposed to be able to be recreated in other labs if one follows the steps, but there are no concrete steps to follow throughout the whole procedure, and there is the ethical issue of using human test subjects. According to the data, Dr. Rascher believed he had figured out how long it takes a body to cool, and that the best re-warming method was a hot bath. Others have argued that neither of those assertions are true, however.

How Do Different Liquids Affect The Rate Of Evaporation

340 Words | 2 Pages

The hypothesis for this experiment was accurate, as the liquids evaporated at different rates. Also, the hypothesis stated that nail polish remover would evaporate at the fastest rate, which it did, at an average rate of 28.2 mL per day. The salt water evaporated at the slowest rate at an average of 9 mL per day. The other liquids evaporated at very similar rates. These results occurred because the characteristics of each liquid effect the efficiency of evaporation.

Water Hydration Lab Report

603 Words | 3 Pages

In this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up

The first experiment demonstrated that when a cracker is placed in an environment with high relative humidity (e.g. 75%) at 25°C, it would absorb moisture from the environment until it reaches equilibrium. The moisture absorbs into the cracker due to its low water activity. The crackers would become soft as moisture is absorbed.
