The Facts About Chlorine - New York State Department of Health.
If the surrounding warm air is cooled it sinks since it is more dense, and at the same time the water as a gas is condensed into tiny droplets of water. Application: Liquid Nitrogen Demonstration The white fog coming from the liquid nitrogen container ( graphic in new window ) is having the same effect as described above.
Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H 2 in H 2 O) and the breaking of hydrogen bonds absorbs heat. With a such a high heat capacity, a lot of heat energy can enter a body of water before the water actually increases.
Hi, water is pretty special, it is actually less dense as a solid than it is at 4 C - liquid! something to do with the rigid bonds that make the solid pushing the H2O molecules further apart than when they were just a pretty cool liquid. as it heats up above 4 C i think it becomes less dense again, probably something to do with the extra energy causing the molecules to buzz around.
The vast majority of water on the Earth's surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live. See Full Answer. 6.
Water is called the universal solvent because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H 2 O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge. This helps water dissociate ionic compounds into their positive and.
A piece of wood will float on water; but, most rocks are more dense than water, so they will sink. Helium is less dense than air, so helium balloons rise. Oil floats on vinegar because its density is less.
