Q. What is the percentage of water in cytosol?
The cytosol is mainly composed of water (approximately 70% of the volume) and proteins (20-30% of the volume) (Luby-Phelps K.
Q. What are the five unique properties of water?
The five main properties that will be discussed in this article are its attraction to polar molecules, its high specific heat, the high heat of vaporization, the lower density of ice, and its high polarity.

Q. Why does solid water or ice float on liquid water?
Like most things that float, ice floats because it is less dense than liquid water. Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top.
Q. Why does ice float biology?
Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. Because ice is less dense than water, it is able to float at the surface of water.
Q. What property lets water float on ice?
Ice floats because it is less dense than liquid water. Density measures how many particles are within a given volume. Usually, frozen things, like ice, are denser than liquid things, like water.
Q. Does ice have more oxygen than water?
The reason why ice is less dense than water has to do with hydrogen bonds. These bonds form because the positively-charged hydrogen atoms are attracted the negatively-charged oxygen atoms of nearby water molecules.
Q. What does it mean that water has a high heat of vaporization?
Heat of vaporization of water That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. This is because the molecules with the highest kinetic energy are lost to evaporation (see the video on evaporative cooling for more info).
Q. Why is specific heat of water so high?
Water has a higher specific heat capacity because of the strength of the hydrogen bonds. It requires a significant of energy to separate these bonds.
Q. When a liquid is vaporized how much energy is gained?
The temperature of the substance does not change during vaporization. However, the substance absorbs thermal energy. Explanation: When Liquid is vaporized it gains energy by 20%.
Q. What property causes water to stick to itself?
Hydrogen Bonds
Q. What is water sticking to water called?
Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.
Q. Why does water make things stick together?
Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged.
