Silica gel is actually a glass-like structure usually found in a bead-like form with the chemical formula of SiO?. Because of its ability to absorb water and a variety of other liquids, it is widely used in industry and as a desiccant. Its ability to absorb a large amount of liquid is...
Why do water molecules stick to other water molecules? Why does carbon tetrachloride not dissolve in water? Why are weak bonds important to living organisms? Why is ice the solid form of water? Explain why hydration is so important.
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Ice is a solid form of water that is unusual in that it is less dense than liquid water. Discuss some implications of this fact. Under what conditions can you have liquid carbon dioxide? What is it called when a gas becomes a solid? a. condensation b. depositio...
Water is unique as a liquid in that it already has 67 known anomalies compared to normal liquids. For example, water has a higher density at 4C, an unusual thermal capacity and very high surface tension. Up until fairly recently there hasn't been a comprehensive explanation for these ...
Ice is water in its solid state, but its unique crystal structure makes it difficult to melt with microwave radiation. According tothenakedscientists, this structure keeps the water molecules from rotating like they do in their liquid state: ...
By contrast, deriving energy from a solid is a much tougher prospect (though there are microbes that eat rock), Glazer said. But the other part of the equation — that water can carry things into and out of the cell — has to do with water's unique chemical configuration. The humble ...
Water hardens into ice (solid phase) when exposed to temperatures below 0 degrees Celsius. However, this is the point where some of water’s unique properties begin to appear. Most other substances take up less volume when they move into a solid phase, meaning that they become more dense as...
Most things have three states:solid,liquid and gas.We can change a solid into a liquid and liquid into a gas.It doesn't matter which of the three states a thing is in,it is still the same thing.Let's think about water to see how this works.Water is one of those things that ...
This technology is used in Thermal Energy Storage Systems (TESS), which provide continuous high-temperature heat or power that is safe, low-cost, long-lasting, and high in capacity. The solid-liquid phase change in the blocks stores significant thermal energy released as they cool and the ...
