Does water expand or contract when it changes from liquid to solid?
when a liquid turns into a solid it contracts
Why does water expand when cold?
Water expands when it freezes because the molecules arrange themselves in a hexagonal structure, with more space between them compared to the liquid state. This increased space results in the expansion of the substance, causing ice to be less dense than liquid water.
When water changes into ice it expands or contracts?
Water expands when it freezes into ice because the molecules rearrange themselves into a more structured hexagonal arrangement, which takes up more space per molecule compared to the random arrangement of liquid water molecules.
Does frozen water weigh more?
No, frozen water weighs the same as liquid water. When water freezes, it expands in volume but maintains the same mass, so the weight remains constant.
Why water expands on solidification?
Water expands on solidification because the hydrogen bonds between water molecules in ice are arranged in a hexagonal structure with more space between the molecules compared to liquid water. This results in a decrease in density and an expansion of volume when water freezes into ice.
What liquid expands instead of contracts when frozen?
Water is a liquid that expands when it freezes. This is due to the unique structure of water molecules, causing them to form a crystalline lattice when frozen, which takes up more space than liquid water.
What is thermal expasion?
Its when a liquid freezes and expands or contracts. Ex. Water when it freezes has more mass than the liquid

What substance is unusual because it expands when it goes from a liquid to a solid?
Water is the substance that expands when it freezes. This expansion is due to the unique structure of water molecules, which form a lattice-like arrangement when frozen, causing it to take up more space than when in its liquid state.
When you freeze water and it expands does it melt more water than before?
No. Under controlled circumstances, when you freeze 1 measure of water, it expands to about 1 and 1/10th of a measure. When melted, it will once again equal 1 measure of water.
Why does ice float into water?
When you freeze water it expands so it is less dense than liquid water therefore more buoyant so it floats.
Does the volume change when a liquid is frozen?
It increases. Think of water: ice cubes take up more space than does the same amount of water when in liquid form.
Why is ethanol liquid?
Ethanol is a liquid at room temperature due to its intermolecular forces. The strong hydrogen bonding between ethanol molecules requires more energy to break the bonds, keeping it in a liquid state.
Why is the water not used in the construction of liquid in glass thermometer?
Water expands unevenly when heated and can freeze at low temperatures, affecting the accuracy of the thermometer. Mercury, which is used in liquid-in-glass thermometers, expands evenly with temperature changes and remains liquid at a wide range of temperatures, making it ideal for measuring temperature accurately.
The tendency to form liquid drops is more or less in water than it is in ethanole?
The tendency to form liquid drops, or surface tension, is higher in water than in ethanol. This is because water molecules have stronger intermolecular forces, such as hydrogen bonding, which lead to a higher surface tension compared to ethanol.
Does water expand or contract when it changes from liquid to solid?
when a liquid turns into a solid it contracts
When water freezes does it shrink or expand?
When liquid water becomes solid ice, it expands. This is because the lattice structure that gives it definite shape forces the molecules slightly farther apart than they are in the liquid. When water freezes, it expands because of its peculiar molecular structure as ice. Instead of molecules fitting nicely together, water molecules form round molecular bonds with a large hole in the center, like a donut. This both makes it less dense than liquid water, and it also makes it expand.
