Does the Source of Water Affect its Evaporation Rate?
Evaporation happens when water molecules turn into gas. Many things can affect how quickly this happens. For example, evaporation occurs faster in warm weather than in cold weather. This is because heat increases the energy of water molecules. The more energy involved, the faster the evaporation rate. Other factors can affect the speed of evaporation too. Anything that slows down water molecules’ movement will slow down the evaporation process. Anything that weakens their bond will speed it up. Pollution can weaken the bond between water molecules, proving that dirtier water should evaporate faster than cleaner water. www.chem4kids.com/files/matter_evap.html

When they bounce into each other, energy switches back and forth between them. Once a molecule has enough energy, it breaks free, turning to gas. This is evaporation. Heat causes more energy during this process, making the water molecules move faster and bounce into each other more often and more powerfully. Just think of a pot of boiling water. You can see the molecules that have broken free and turned to gas rising from the pot in the form of steam. Outside forces affect the evaporation process. www.chem4kids.com/files/matter_evap.html
Water molecules like to stick together. This habit of theirs is called “inter- molecular attraction” When the bond between water molecules is very strong, it takes longer for them to break free and turn to gas. Therefore, strong bonds make the evaporation When water molecules are kept from sticking together, the liquid evaporates faster. Inside forces affect the evaporation process. 2daysscience.blogspot
The release or agitation of the water would release the co2 causing the water to rise and evaporate.
When something boils it evaporates because the liquid molecules gain enough energy to escape the system and become gas. When this happens we see steam, or water vapor.
The viscosity of water can be affected by temperature, and by pressure and temperature, but not by pressure on its own. As a liquid, it is incompressible and so isn’t affected much by pressure. As the temperature applied to water increases, it starts to become unstable, like when water in a pan begins to boil and it starts to bubble. When water reaches its boiling point, its state changes from a liquid to a gas, and it becomes steam.
This is my research report on my science project. My topic is What Clear liquid affects the rate of evaporation. I chose this topic because I wasn’t able to choose a project I wanted to do. So I looked through the list and saw this topic. Then suddenly I think back to a wet afternoon and very cold a few years ago. That morning I saw a puddle of water and when I came back it was half way drained down. So i thought back to that moment long ago which I still remember. And so not only I needed a project, I also was a little interested into this topic. I was also interested into rates of evaporation when I saw this question. The question i’d be answering is What clear liquid has a faster evaporation rate.
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).
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).
The bond between the compounds and the water molecules is weak and therefore easily broken. Typically, these bonds are broken through the heating of the compound.
I started to wonder how fast does dry ice evaporate and does a different liquid make it evaporate faster or
Evaporation- when water evaporates in the form of water vapor by the heat of the
Have you ever wondered why rain drops form little bubbles, or how water makes little bubbles on pennies? To properly understand my project, you will have to understand water surface tension, and how hydrophobic and hydrophilic molecules work. Also how surfactants work, and how surfactants can propel a (n) object.
This happens due to osmosis because the boiling water doesn’t have any solute compared to the spaghetti. That means the spaghetti is a hypertonic solution, while the boiling water is a hypotonic solution because the water was absorbed from the pot (hypotonic) to the spaghetti (hypertonic). If I were to do an experiment that is related to this one, I would like to learn more about the other factors that affect
The use of magic, activating the imagination and sparking the childlike thoughts we lose as we get older is what Shakespeare intended to project by the use of magic and the belief that magic is real. “ The fairies who haunt the pages of A Midsummer Night's Dream stand for "those pretty children of our childhood." (Ciraulo, 1999). Shakespeare’s use of magic and fairies brings the light heartedness and childlike wonder as he shows how these elements affect each character in the story with his belief of magic.
Intermolecular forces hold molecules together when they are in solid or liquid state. However, water has the ability to dissociate many salts and ionic compounds. This is called dissolving. When NaCl is added to water, it dissociates into the ions; Na+ and Cl- . The positive sodium ions are surrounded by the slightly negatively charged part of water molecules (i.e. oxygen) in the water molecules and the negative chlorine ions are surrounded by the slightly positively charged part of water molecules (i.e. the hydrogen). The kinetic energy of the sodium chloride molecules increase with temperature. This destabilizes the solid state that it is currently in. This increased motion means that the molecules are less able to hold together and as such they dissolve at faster rates and larger amounts.
Water has a high specific heat capacity compared with other liquids. This means that a large increase in energy results in a comparatively small rise in the temperature of the water. This is because much of the heat absorbed is used to break the hydrogen bonds that hold the molecules together. Water is good at maintaining its temperature at a steady level, irrespective of fluctuations in the temperature of the surrounding environment. This is important because the range of temperatures in which
