Cold Water Is Dependent On The Percentage Of Water Essay
Dependence of temperature on the percentage of water mass
Introduction
I always add cold water to my coffee before I drink it, in order to cool it and so not burn my tongue. So I have always wondered how the cold water is able to drop the temperature of the hot water. Does the hot water really change even by adding small amount of cold water? Is the temperature of the hot water is dependent on the mass of the cold water? Therefore, in order to find the answers to these questions, I will experiment with different masses of cold and hot water, in order to examine whether the temperature is dependent on the mass (percentage) of water.

The reason for this is because the hot water will lose heat to the cold water and so the cold water will increase in temperature.
While the water was heating, I measured the amount of the room temperature water used. The main aim for my experiment is to study how the mass has an effect on the temperature. Also, because I am finding the percentage, so the mixture of both quantities will add up to 100 liters of water. Therefore, the mass of both (hot and room temperature water) will vary every trial. However, both quantities will have the same mass when it is 50% of each.
So after mixing both quantities, the temperature was recorded quickly before it cooled. After the hot water was heated (I waited till the water was more than 100, because it drops very fast) I poured the hot water into a cup, I added the room temperature water, then I stirred it and measured the temperature of the mixture. Also, in order to record the most precise temperature, I would set the thermometer in the middle of the cup and not touching the sides or bottom of the cup and I would wait for it till it stabilized before recording the

This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.

I then added this water to the beaker that contained the mixture I created from the last step of the experiment. I also gathered 2 boiling stones and added them to the mixture of the last step. I placed the beaker on a hot plate and heated it up to 130 degrees Celsius.

630 Words | 3 PagesIntroduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
Essay On The Effect Of Temperature On Osmosis
1159 Words | 5 PagesWhen temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher

802 Words | 4 PagesIntroduction: In this assignment, I will be doing two experimentations on examining the impact of temperature on the Alka-Seltzer’s response time. The first experimentation that I will be doing involves some water that is room temperature. The second experimentation that I will be doing involves some water that is very hot. If I want to be able to figure out the impact of the temperature on water, I will have to document the time it will take for the Alka-Seltzer to go into solution.

The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

Then our results ρ vs T and also density vs temperature values given in the Steam Tables were plotted on the same graph in order to compare. In the second part the density of water was measured by density bottle. The densities obtained from the experiment are 995, 992.5, 991, 990 kg/m3 for the first part and

However, it is now known that that is not the fact, and that adding salt will do the opposite and make the water boil more slowly instead.

Calorimetry Lab Report
747 Words | 3 PagesThis measurement is accurate to Dr. Wile’s description of the outcome. He said, “Metals have small specific heats, so it [the answer] should be less than 1 J/g˚C.” Calorimetry is the science of determining the changes in energy of a system by measuring the heat exchanged with the surroundings. Calorimetry experiments are performed in order to determine the heat flow between two substances and a calorimeter is used. A calorimeter is a device that is used to measure the amount of heat transferred to or from an object. The science of calorimetry is that the energy gained or lost by the water is equal to the energy lost or gained by the object.
Water Hydration Lab Report
603 Words | 3 PagesIn 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
