Both molecules are made up of 2 hydrogen and 1 oxygen, referring to its atoms.
Ice molecules have a lower energy content.
The molecule (chemical formula) is the same - H2O.
If you mean the smallest particle of water that has the properties of water, then yes, water particles are molecules.
Yes
A liquid has the same molecules as a solid, plasma, or gas. The only difference is how close together they are, or, in other words, the desity.
The volume of a 100 milliliters of liquid water would be less if it were frozen. Water as ice (i.e. solid), is less dense than water as a liquid. The water would have the same mass whether solid or liquid, but its molecules occupy more space as a solid than they do as a liquid. This is a very unusual natural phenomenon, which is good for us or any frozen bodies of water would have all the life in it crushed by sinking ice!
The molecule (chemical formula) is the same - H2O.
Solid, liquid or gas water remain the same molecule - H2O.
no
It's particles spreadf apart.
Yes, it is possible to have steam, liquid water, and ice exist in the same space, but not a molecule of water can only be in one of the three phases.
Weather a thing is solid, liquid or gas depends upon the force of the bonds between the molecules, and that depends one temperature and pressure, as well as the particular molecule. In a solid force between molecules is greater as then the forces between molecules of the same material as a liquid, and in a liquid is greater than in a gas. So in the environments most often found on the surface of the earth, hydrogen as a molecule consisting of two hydrogen atoms is always a gas, but water, consisting of two hydrogen atoms and one oxygen atom, can be solid (ice), liquid (water) or gas (water vapor), depending on the temperature and pressure. when you boil water, you turn the liquid into a gas. When you freeze water, you turn the liquid into a solid.
If you mean the smallest particle of water that has the properties of water, then yes, water particles are molecules.
yes because the atoms of two gases, hydrogen and oxygen, can combine together to form water, which is a liquid............
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
It's exactly the same size as a water molecule or an ice molecule.
Yes
A thing's heaviness is a measure of gravity's effect on its mass. Molecule for molecule, H2O (water) is heavier than O2 (oxygen); however, you are comparing two different molecules at two different pressures and densities. Oxygen, while lighter than water (molecule for molecule) at normal pressures, is much heavier when compressed to the point of condensation. Liquid oxygen has a weight of 1.141 g/ml, whereas water's weight is 1 g/ml. They are very close to the same weight, but liquid oxygen is almost 15% heavier.
