Water expands when it freezes because, due to the hydrogen bonding, it forms a tetrahedral lattice. Other things that expand when frozen include silicon, bismuth, antimony, gallium, and germanium

Yes, freezing an object can cause it to expand. Water, for example, expands when it freezes, which is why ice cubes take up more space than liquid water. This is due to the formation of a crystalline structure in the freezing process, which requires the molecules to move further apart.
they expand
No, although it does expand with heat as do most substances.
By maintaining the temperature over the freezing point.
A freezing mixture is a combination of substances that, when mixed together, can lower the temperature significantly, often below the freezing point of water. Commonly, it consists of ice and salt, where the salt lowers the freezing point of the ice, allowing the mixture to reach temperatures suitable for freezing or chilling other substances. This technique is frequently used in laboratories and culinary applications, such as making ice cream.
It will shrink!
No only water it's the odd one.
Freezing a rock would shrink it some (contract) while the thawing would expand it. This applies to most substances, water being the obvious exception.
Gallium, silicon, and bismuth exhibit unusual expansion on freezing due to the way their crystal structures change upon freezing. The crystals of these elements have an open or less dense structure in the solid phase compared to the liquid phase, leading to expansion upon freezing instead of contraction.
Yes.
Like water, antimony, bismuth, silicon, and gallium also exhibit anomalous expansion behavior, where they expand upon solidification. This is due to the unique arrangement of atoms in their crystal structure, which causes them to expand instead of contract when transitioning from a liquid to a solid state.
Freezing water causes it to expand and form a solid structure, changing its physical properties. The solid ice is less dense than liquid water, which is why ice floats. Additionally, freezing water can affect its transparency and ability to dissolve other substances.

yes
Yes.
Most substances expand as their temperature increases. One exception that I can think of is water, when it is near freezing. Water at 4°C will expand when cooled to 0°C, then as it freezes to ice it expands. This is why ice floats in water.
