Questioning and Predicting Questioning • What will happen when adding a small amount of liquid? • How will the mixture change with different amounts of water? • What happens when you poke your fingers into the Oobleck? • How can you mould the Oobleck? • Can you hold the mixture? • How long will the ball hold into a ball? • How can you make the Oobleck move into a liquid? • What happens when you try to make a ball? • Can you try and use all the Oobleck into one ball? • How can we make the Oobleck into a sold? • How long will it take for the Oobleck to melt back into a liquid from a ball?
The Water Cycle Water is continuously moving and changing states from liquid to gas (vapor) and solid (ice, snow, and hail). The water cycle describes the movement of all water on Earth. The Earth's water is constantly moving through this cycle, which has no beginning and no end.
Do All Liquids Evaporate At The Same Rate? Have you ever wondered what is left after something evaporates? Evaporation is a very interesting topic, that is one of the reasons I chose this. I have learned so much facts about evaporation while researching it. Some things I never thought I would
From the results that were collect throughout the experimental investigation has proved the hypothesis to only be partially right. Multiple tests were made when conducting the experiment, two clear solutions were combined at various temperatures and concentrations. The hypothesis states that by adjusting the concentration of the reactants will cause the reaction to either speed up at a higher concentration or slow down at a lower concentration. In the reaction temperature should have a similar effect on the experiment, in that increasing the temperature will cause an increase of particle movement and cause more collision, thus increasing the reaction rate. Therefore decreasing the temperature will decrease the rate of the reaction. From the results given in Tables 2 and 3 it shown that every time the concentration is halved the time is increased. When the concentrations of both KIO3 and NaHSO3 are decreased the time has increased, some concentrations having a higher increase than others. In each concentration decrease the time is at least doubled from the previous concentration time, which is therefore increasing the rate of the reaction.

July 19, 2016, http://aquacycle.blogspot.com/2010/07/water-cycle.html Evaporation Evaporation is a process in the water cycle when a liquid is Water storage can be either fresh water or salt water. Ground water is where there is just a body of water, or water that is on the ground. Also water storage does not have to be in liquid form. It can be found in snow, ice, or glaciers. When one of the solid forms of water melts it is called run off water. When run off water runs into a water storage it will evaporate at some point in the future.
2Q. How is the term related to the properties of matter 2A. Evaporation is related to the properties of matter because it is a liquid and a gas. We know this because there are three states of matter which are soild, liquid and gas since evaporation first starts as a liquid (water). Then it turns into gas (cloud).
In this document, I jotted down some notes while putting together the reading material. These notes point out some of the reading content to pay particular attention to. The notes are divided into section headings based on the reading material. This is not meant to be a complete list of
The water cycle represents how water is exchanged and cycled through Earth’s land, oceans, and atmosphere (2010 pg.1). Evaporation, condensation, and precipitation are all three main factors within the water cycle. Evaporation occurs when a liquids surface changes to gas. For example, when water from rivers, oceans or lakes evaporate, it becomes water vapor. Condensation occurs when gas changes to a liquid. For example, clouds form when water vapor condescends. Precipitation is described as any liquid or solid water that falls to earth from above. A great and simple example would be rain, snow or hail (2010 pg.1). Within the water cycle, there are three states of water: solid, liquid and gas. Most of Earth’s freshwater is
Evaporation (transpiration) Heat from the sun warms water from rivers, lakes, and the ocean to turn into vapor or steam; leaving the reservoir and moving upwards into the atmosphere. (Plants transpire, or lose water from their leaves).
I started to wonder how fast does dry ice evaporate and does a different liquid make it evaporate faster or
The beginning of the water cycle is evaporation. My experience with evaporation is really fun! You get to take a fun ride high up in the sky and suddenly
The results show that HCl had the highest decay rate. Distilled water increase in mass and orange juice showed the least amount of decay. Comparing the two sodas together the darker soda, coke, was the worse compared to the lighter soda, citrus twist. The monster energy drink was found to be the most harmful for your teeth, being a drink unlike HCl which is not a something at you can drink. HCl is not something you can drink it was used as an extreme for the tooth to show the decay rate. Distilled water is used as controlled group. The conditions unlike reality were exposed to this solution for weeks without being brushed. When looking at the data collected for the first week the tooth in the distilled water increased in mass due to the tooth
Water is a substance that is constituent of earth’s streams, lakes, and oceans. But water is also present in the atmosphere. As mentioned before there’s water located in the atmosphere. Nearly all of the water is located in the lowest layer of the atmosphere also known as the troposphere. We cannot feel or see this this water because “it is present in variable amounts in the atmosphere, from 0% to 4%” (“Water in the Atmosphere”). This is the main reason why we cannot see nor feel the water in the atmosphere. If we think about it there almost no water in the atmosphere because earth is huge and 4% of water spread all around the world is a little bit.
Figs 2 – 4 displayed the binary mixture droplet surface plots as a function of time at the volume ratios of 3:1, 1:1 and 1:3, respectively. The higher slope value indicated the higher evaporation rate. The evaporation rate of the pentadecane single component droplet was 6x10-10m2/s and of the dodecane single component droplet was 3.25x10-9 m2/s. At the volume ratios of 3:1 and 1:1, the changes of the droplet diameters obtained at the backward region (MDRs) were observed at the end of the experiment. The droplets left the forward region and then stopped at the backward region. When the droplets stop, the change of the diameter was obtained by MDRs at the backward region. However, for the pentadecane and dodecane binary mixtures at the
Experiment 2: Intermolecular Forces Performed: 9/12/2011 Submitted: 9/20/2011 Chemistry 1046L PART I: Purpose: The purpose of partI in this experiment is to identify a variety of unknown substances’ properties using observations of the temperature changes that occur during evaporation. We know that substances with weaker intermolecular forces, such as London dispersion, will have a faster vaporization rate and thus a higher temperature difference compared to those with stronger molecular bonds such as hydrogen and dipole-dipole forces. By measuring the average kinetic energy (or the temperature) of the liquid left behind after some evaporation takes place, we can determine its type of intermolecular
