I'm on the same question... 2005 Tuesday 7 June Science Chemistry C.E Paper!!
When water gets cold, it can freeze and turn into ice. The molecules in the water slow down and come together, forming a solid structure. This process is known as freezing.
Water is a bad Conductor. Note this point! When water at the bottom of the vessel gets heated first, it expands. So its density goes lower. But the comparatively cold water at the top would be with higher density and so they would come down allowing lower dense water to move up. This gets repeated and thus convection current gets produced.
Water is unique because it expands when it freezes, unlike most substances that contract. This is because water molecules form a crystal lattice structure when freezing, causing them to push farther apart. This property is why ice floats on water, which is crucial for aquatic life during winter.
the water gets into cracks of the rock then over time if the water doesn't evaporate it freezes and expands. When the ice expands the crack gets bigger when the crack gets big enough it splits the entire rock
because the mixture of ice and water has an equilibrium temperature of 0 C and thus it will be the first calibration system and making sure that thermometer is working properly. The thermometer will have better contact with the water than with lumps of ice and therefore adjust better to its temperature.
that water expands when it gets cooler , other forms of matter expands when it gets hotter.
When water gets into cracks and it gets cold, obviously it freezes. When water freezes it expands. As the ice expands, it breaks apart the surrounding material and makes the crack bigger, causing more damage.
Water expands when freezing.
Water expands when it freezes. In winter, water gets into minute cracks in the rocks and then as it freezes it expands and makes the cracks bigger. So more water gets in then freezes so the cracks get bigger still until the rocks break apart.
i know that when water freezes it expands and its volume gets larger but i am not sure how much.
Water is a liquid that expands as it gets colder due to its unique property of maximum density occurring at 4 degrees Celsius. As water cools below this temperature, it forms a lattice structure with hydrogen bonding that causes it to expand and become less dense, leading to the phenomenon of ice floating on water.
its gets cold Actually the ice gets warmer. Its the water that gets cold.
When water gets cold, it can freeze and turn into ice. The molecules in the water slow down and come together, forming a solid structure. This process is known as freezing.
No, water should not be kept in your pool all winter. When it gets cold enough, the water will freeze. When water freezes, it expands. So when the water in your pool freezes and expands your pool will be ruined.
acid gets diluted
Say some water gets into the crack inn a rock, the water freezes and scince water expands when it freezes the rock cracks even more.
popcorn gets different shapes because as the water in the kernel gets hotter it starts boiling and expands creating different size and shapes popcorns
