Frozen water expands, while other frozen liquids contract.

Frozen water (ice) is less dense than liquid water, which is why it floats. When water freezes, its molecules form a crystalline structure that causes it to expand, unlike most liquids that contract when they freeze. This expansion is why ice floats on water.
No, not all liquids and gases freeze in the same way as water. The freezing point of a substance depends on its chemical composition and molecular structure. Different substances will freeze at different temperatures.
Water, juice, milk, and coffee are examples of liquids.
Liquids can float on each other due to differences in their densities. When a less dense liquid is poured on top of a denser liquid, it will float because it is lighter and less likely to sink. This is known as stratification, where liquids of different densities form layers with the least dense liquid on top.
Different liquids can affect sound in various ways depending on their density and properties. Liquids like water and oil can absorb sound waves and dampen vibrations, resulting in a muffled or distorted sound. Thicker liquids with higher viscosity can slow down sound waves as they pass through, changing the pitch or frequency of the sound. Additionally, some liquids may resonate at specific frequencies, amplifying certain tones or frequencies.
Yes, sound waves can pass through liquids. The speed of sound in liquids is faster than in gases and can travel long distances through water, for example. Sound waves can also change direction and speed as they travel through different liquids with varying densities.
