This is due to hydrogen bonding and the shape of the structure formed. This bonding is a weak intermolecular attraction caused by the electrostatic attraction between the positive dipole on hydrogen atoms within a polar molecule (caused by electronegativity differences) and the lone pairs of electrons on another atom.
On cooling, empty spaces are created between structures of water molecules, which have arranged in a sort of hexagonal cross-sectioned tube. No further water molecules can fit in these gaps because of the size; this results in a large empty volume, decreasing the density of the solid or alternately expanding the volume of the substance.
What else can I help you with?
Does methane expand when it solidifies?
Yes, methane expands when it solidifies. This is known as the "anomalous expansion" of methane, which means it becomes less dense when transitioning from a liquid to a solid state.
Which liquid solidifies after heating?
Water solidifies into ice after being heated and then cooled back down.
How many moles of H2O are present in 75.0g H2O?
There are 4.17 moles of H2O present in 75.0g of H2O.
If butter solidifies the process is called?
If butter solidifies, the process is called crystallization. This occurs when the liquid fat molecules in the butter align and form a solid structure, resulting in a firm texture.
What process is described by the equation H2O liquid gives H2O solid plus heat?
H2O(l) --> H2O(g) + heatshows the process of freezing.
Does jello expand when set?
Jello does not expand when it sets. It solidifies and retains the shape of the container it is placed in.
Does methane expand when it solidifies?
Yes, methane expands when it solidifies. This is known as the "anomalous expansion" of methane, which means it becomes less dense when transitioning from a liquid to a solid state.
Give examples of expansion of solids?
All solids expand when they are heated. Examples include concrete slabs having spacers between them to accommodate expansion, and balloons expand with air being pumped into them and contract when air is let out.
Which liquid solidifies after heating?
Water solidifies into ice after being heated and then cooled back down.
What does lava transform into as it cools and solidifies?
As lava cools and solidifies, it transforms into igneous rock.
When an object solidifies what does it get?
hard
What are H2O vacuoles?
H2O vacuoles are structures found in plant cells that store water. They help regulate the water content in the cell and maintain turgor pressure, which is important for cell structure and function. These vacuoles can expand or shrink depending on the water needs of the cell.
Magma cools and solidifies to form what rocks?
igneous rocks
When magma cools and solidifies it becomes which rock?
When magma cools and solidifies, it becomes igneous rock.
When molten rock hardens and solidifies which type of rock is formed?
When molten rock solidifies it forms igneous rock.
Can a ping pong ball with a dent be placed in boiling H2O anddent will go away?
Yes. The hot water will make the air inside the ball expand, removing the dent.
What enzymes solidifies milk?
rennin
