What Are The High Specific Heat Of Water

The salt molecules interfere with this equilibrium by surrounding the water molecules and decreasing the attraction of the water molecules between one another (“Chemistry: the effect of salt…”) and slowing them down (“Can Sea Water Freeze?”). This causes the overall temperature of the substance to decrease due to the slowing movement of the water molecules.

This could affect the point which the substance would get hot enough to evaporate into the air. These could all be very reasonable reasons that the liquid could be evaporating at different rates than natural

Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water. Water composed of two negatively charged oxygen atoms and one positively charged hydrogen. When the temperature is cooler these particles encompass less energy and there is less change that they get separated from each other. In contrast atomic particles are more energetic when the temperature is warmer ands so they will get separated from the hydrogen atom. So cold water holds more oxygen (Mallya 2007). Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water.

(1) According to David Perkins, when a liquid is evaporating it's just molecules that are escaping into the air as a gas. In order for the molecules to be able to escape certain energy is needed,the molecule determines the amount of energy that's gonna be used. As an example he used the juggling of a tennis ball compared to a bowling ball. He says that it's gonna be harder to juggle a bowling ball because it has a bigger mass compared to the tennis thus causing more energy needed in the bowling ball. One of the factors affecting evaporation would be the mass of the molecules in the liquid. Another factor would be how stuck the molecules are together, if the molecules are stuck together and have a strong connection, evaporation would be much

This means that, if the substance and the chemicals inhabiting the substance deal with a certain change in their environment, they react in ways to try and either fight off that change or adjust to the change so that there is a balance in the new setting. For example, the solubility of CO2 is greater in cold water vs. hot water. This is because when the temperature rises above the level CO2 is already capable of dissolving from the body of water, the heat reaction causes the solubility ability of CO2 to decrease making the reaction exothermic. Now if the temperature is lower than the average level of heat that can cause the CO2 to separate from the liquid substance, than the solubility increases and the reaction becomes endothermic since

The hydrogen bonds that are formed between liquid water molecules are so strong that they can absorb tremendous amounts of heat energy when breaking. These hydrogen bonds breaking prevent large temperature increases from occurring instantly. A couple benefits include preventing car engines from overheating and maintaining the human body’s temperature. Since the body is mostly

In this project the idea on which liquid would evaporate the quickest. The cooking oil should evaporate the quickest because it is the lightest liquid coming in at 1.01 which has the least density out of all of them. Density is the degree of compactness of a substance. The other liquids density come close but are not the lightest. Water has the density it has because after evaporation comes precipitation . How is evaporation helpful or dangerous to our society? Evaporation is great it gives

are still able to move, but they are now slowed to a vibration type of movement.

When molecules of water evaporate, heat from the object they evaporated from goes with them into the air. The heat is called latent heat, and it’s inside the water molecules. This also lowers the temperature of the object the heat came from. Evaporative cooling is when an object cools down because of evaporation. When you exercise and it’s hot outside, your body sweats. When your body sweats, evaporation causes the water on your body, or the sweat, to eventually evaporate, or rise into the air. This action

The ocean has existed for around 4.6 billion years after the Earth was created. It plays an essential part in order to maintain life on Earth by maintaining the habitable climate. Due to the ocean, the Earth is able to sustain moderate weather and temperature, in contrast to the moon, which has extreme temperatures. The ocean and atmosphere are tightly linked, so when one fluctuates, the other will too. For example, weather in the atmosphere can directly affect the ocean’s temperature and currents. Also, the ocean plays a critical role in storing heat where the ocean is able to absorb more heat and it will take longer time for the ocean to revert to normal. After the heat has been absorbed, the ocean currents will transport the heat and influence the climate. The ocean has a major impact on global climate because of its connection to the atmosphere and abilities to store, and transfer heat around the Earth.

Water is a much better conductor of heat than sand, which leads to more energy from solar radiation being distributed throughout large depths of water in the ocean. Energy is further distributed throughout the ocean by the constant mixing and movement of liquid water. This distribution of heat energy leads to little energy being transferred back to the surface atmosphere. Sand is a poor conductor of heat, so heat does not distribute throughout sand particles beneath the surface and sand does not mix in the way water in the ocean does. Sand more quickly absorbs solar radiation and then transfers this heat to the surface atmosphere, which causes the surface atmosphere to have larger temperature variances.

Increased blood flow to your skin and sweating causes dissipation of heat, and body temperature remains within normal limits.

Water temperature is important as it influences the water chemistry. As the temperature increases the amount of oxygen held begins to decrease, this decrease in oxygen may not be sufficient for aquatic life. Water temperature also affects the photosynthesis of aquatic plants, sensitivity to pollutants, and the organism's metabolic rates. A measured water temperature of 22℃ is within the ideal water temperature range. Water temperature varies due to air temperature, shade, and deeper water temperature.

A water molecule consists of two hydrogen atoms and one oxygen atom. These atoms are held together by a polar covalent bond in which both hydrogen atoms each share one electron with the oxygen atom. Because oxygen has a very high electronegativity value, it has the tendency to steer electrons away from the atom that they are connected to. So the oxygen atom, having more electronegativity than the hydrogen atoms, will pull the electrons towards it. This causes the shared electrons to actually spend more time with the oxygen atom than the hydrogen atoms. Because of this, the oxygen atom becomes slightly negatively charged while the hydrogen atoms become slightly positively charged. When group of water molecules are together the negatively charged oxygen atom of one water molecule will then be attracted to and bond with the positively charged hydrogen atoms of another water molecule. These bonds are called hydrogen bonds and they are responsible for most of water’s properties. For example, it is the

The purpose of this lab is to determine how temperature changes when six different liquids evaporate and then rank the substances in terms of relative strength of their intermolecular forces. The hypothesis for the lab was, If the substances without hydrogen bonds, they would end in smaller change in temperature. Evaporation is vaporization that occurs at the surface of a liquid. There are three types of intermolecular forces which are Hydrogen Bonding, Dipole-Dipole,
