A correct statement about a sample of liquid water is that it consists of molecules made up of two hydrogen atoms bonded to one oxygen atom (H₂O). In its liquid state, water molecules are in constant motion, allowing for intermolecular hydrogen bonding, which gives water its unique properties like high surface tension and the ability to dissolve many substances. Additionally, liquid water is denser than ice, which is why ice floats on water.
What else can I help you with?
What happens to the molecules that make up a sample of liquid water when the sample absorbs molecules that make up a sample of liquid water when the sample absorbs enough heat to reach the boiling poi?
When a sample of liquid water absorbs enough heat to reach its boiling point, the increased thermal energy causes the water molecules to move faster and break the hydrogen bonds holding them together. As the temperature reaches 100°C (at standard atmospheric pressure), the molecules gain enough energy to overcome these intermolecular forces, transitioning from the liquid phase to the gas phase, resulting in the formation of water vapor. This process is known as vaporization or boiling.
How is the density of a small solid sample whose mass and volume is difficult to measure is determined?
Use a container with a liquid (water). Mark the level of the liquid on the container. Insert the small solid sample. Mark the level of the liquid now on the container. compute the difference between the two marks. You can use traditional computation for calculating volume.
Which best describes the total mass of a sample of water when it condenses from a liquid to gas'?
The total mass of a sample of water remains constant when it condenses from a liquid to gas, according to the law of conservation of mass. Although the state of the water changes, the mass does not change during the phase transition. Therefore, the total mass of the water in both the liquid and gaseous states is the same.
Why do you use filter paper to remove soil impurities from a sample of water?
Filter paper is used to physically separate solid impurities, like soil, from a liquid sample of water through the process of filtration. The filter paper acts as a barrier that allows the liquid to pass through while trapping the solid particles. This helps in effectively removing the soil impurities from the water sample.
Which best describes the total mass of a sample of water when it condenses from a liquid to a gas?
The total mass of a sample of water remains constant when it condenses from a liquid to a gas, according to the law of conservation of mass. Although the water changes state, transitioning from liquid to gas involves energy changes rather than mass loss. Therefore, the mass before and after the phase change is the same.
What is the process of liquid water changing to liquid water?
Condensation is the correct term.
What is the Correct procedure for handling sample of pond water?
place the sample on the microscope slide and observe it.
Is 'fed water' a correct statement?
No, 'fed water' is not a correct statement. The term 'fed' is typically used in the context of providing food, not water. It would be more accurate to say 'given water' or 'provided water'.
How is a sample oxygen different from a sample of a water?
A sample of oxygen is a pure gas composed of oxygen molecules (O2), while a sample of water is a liquid composed of hydrogen and oxygen atoms (H2O). These substances have different physical properties and chemical compositions, with oxygen being a gas and water being a liquid at room temperature.
Is when water vapor turns into liquid water?
Yes, it is correct.
The relative concentration of water molecules in a liquid sample is called?
specific gravitythe relative concentration of water molecules in a liquid sample. A clinical lab test that measures specific gravity in a sample of urine is made to evaluate filtration and water reasborption in the kidneys, using a urinometer.

How much energy flow is involved when changing a sample of water from a liquid to a gaseous?
google "water heat of vaporization"
The process of water vapor changing to liquid water is?
Condensation is the correct term.
How much water doea mars have?
Mars has no liquid water. For a planet to have liquid water it must be the correct distance from the Sun like Earth.
