Which one best explains why icebergs float?

Ice is less dense than water. When liquid water freezes, its particles expand, increasing in volume. Therefore, it becomes less dense than water.This causes the iceberg to float on the water Because it is less dense compared to liquid water caused by the expansion of its particles.

Why do icebergs float?

Icebergs are thick chunks of ice floating in the ocean.The reason ice floats and is lighter than water is A certain mass of ice takes up more space than the same mass of water. This is related to the nature of hydrogen bonding. This iceberg floats on the Otago coastline.

Which best explains the high surface tension of water?

The high surface tension of water is due to Molecular interactions that exist between water molecules. There is cohesion between molecules in water. This high surface tension is also due to the polarity of the water molecules.

Which best explains why water has a high specific heat?

The high heat capacity of water is Properties caused by hydrogen bonding between water molecules. After absorbing heat, the hydrogen bonds are broken and water molecules can move freely. When the temperature of water is lowered, hydrogen bonds are formed and a lot of energy is released.

Which best explains why if a glass of water can stick to one side?

Which best explains why water is able to « stick » to the sides of glass? … There is strong adhesion between glass and water molecules.

Which of the following best explains why a paper clip can float on water for 2 points?

high surface tension Help paper clips – with higher density – float on the water. The cohesive forces between liquid molecules are responsible for a phenomenon called surface tension.

Which is least likely to be a freshwater reservoir?

ocean Least likely to be a reservoir of fresh water.

What is the high specific heat of water?

Some substances heat up quickly, while others heat up slowly. Water is one of the latter – it has a high specific heat capacity because it requires more energy to raise its temperature.The specific heat capacity of water is 4182 J/kg °C.

What gives water such unique properties?

unique properties of water

Water molecules are polar, The hydrogen part is positively charged, the oxygen part is negatively charged, and the overall structure is curved. This is because oxygen is more electronegative, which means it is better at attracting electrons than hydrogen. Water is an excellent solvent.

What is a real world example of surface tension?

water walking: Small insects such as water striders can walk on water because they are not heavy enough to penetrate the surface. Floating Needle: A small, carefully placed needle can float on water, even though it is several times denser than water.

Why does salt water have a higher surface tension than water?

Due to its electrical charge, water molecules are tightly bound to ions. stronger than they are towards each other.So add salt Networks that strengthen intermolecular bonds in water. Therefore, since surface tension is caused by intermolecular bonds, the stronger the intermolecular bonds, the higher the surface tension.

Why does water have high surface tension but low viscosity?

The high surface tension of water is due to hydrogen bonding in water molecules…water has very strong intermolecular forces and therefore has a low vapor pressure, but it is even lower compared to larger molecules with low vapor pressure. Viscosity is the property of a fluid that has a high resistance to flow.

What if icebergs don’t float?

When ice forms at the top and sinks to the bottom, they freeze up from the bottom. …if the ice doesn’t float, Underwater life is impossible! When water freezes on top, the ice floats. It stayed on top and the ice slowly thickened, freezing our lakes and ponds from top to bottom.

Why are 90% of icebergs underwater?

Density also explains why most icebergs are below the ocean’s surface.because The density values ​​of ice and sea water are very close, the ice floats « low » in the water. … which means that ice is nine-tenths as dense as water, or 90% of water, so 90% of icebergs are below the water’s surface.

Why do icebergs float instead of sinking to the bottom of the ocean?

Believe it or not, ice is actually 9% less dense than water. Since water is heavier, it displaces lighter iceso that the ice floats to the top.

What properties of water are most important?

One of the important properties of water is that it is composed of polar molecule: Hydrogen and oxygen in a water molecule (H2O) form a polar covalent bond.

What are the three most important properties of water?

The main properties of water are Polarity, cohesion, adhesion, surface tension, high specific heat and evaporative cooling. Both ends of the water molecule are slightly charged. This is because oxygen is more electronegative than hydrogen.

What are the three main characteristics of water?

physical properties of water

  • Color – Pure water is colorless; colored water can indicate pollution. …
  • Turbidity – pure water is clear and does not absorb light. …
  • Taste and smell – Purified water is always tasteless and tasteless.

What is Q in Q MC Δ T ?

Q = mcΔT. Q = thermal energy (Joules, J) m = mass of substance (kg) c = specific heat (units J/kg∙K) Δ is a symbol meaning « change »

How does the high specific heat of water affect your body?

Water has a relatively high specific heat or heat capacity, which means it can absorb a lot of heat before the temperature rises. This feature helps it stabilize the temperature of the surrounding environment. … water evaporates from the skin and lungs to cool the body.

Why is the heat capacity of water high?

Water has a higher specific heat capacity Because of the strength of hydrogen bonds. It takes a lot of energy to separate these bonds.

Which is most likely to be a freshwater reservoir?

Most fresh water is trapped in the form of ice Greenland’s vast glaciers and ice sheets. Storage locations for water such as oceans, glaciers, ponds or even the atmosphere are called reservoirs.

Which could be a freshwater reservoir?

the answer is ocean. The ocean contains a high concentration of salt, so even if it rains a lot, the ocean is still salty. If you want to get fresh water from the ocean, for example you have 100 ml of salt water, then you will only get about 10 ml of fresh water and the rest is salt.

Which example best illustrates adhesion?

Water droplets are made up of water molecules that like to stick together, which is an example of cohesion.This Water droplets stick to the ends of pine needleswhich is an example of adhesive properties.
