What is the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure?
The ratio of the average velocity of hydrogen molecules to neon atoms is the square root of the ratio of their molar masses. Since the molar mass of neon is about 20 times that of hydrogen, the average velocity of hydrogen molecules would be about √20 times faster than that of neon atoms.
Are the molecules in ice packed more tightly than the molecules in water?
Compared to a solid object's molecules no. Unless the water is ice. Water molecules are more compact than gaseous molecules.
Which 1 has more molecules 9 g of water or 9 g of sugar?
9g of water
Why two different liquids could haved ifferent densities?
They can be made of different atoms, different masses of the atoms, different sizes of the atoms. Mercury atoms are very small, and very heavy. Bromine atoms are larger and lighter. For molecular substance another factor becomes important. Who well the molecules fit together, How much empty space is still there between the molecules because of how the can pack together. Water molecules pack very well together. Gasoline molecules do not pack as well. The molecules of gasoline are larger and more complex, but the density is less than water because of how much better water molecules pack together.
Why does cold water have more molecules than hot water?
You may want to frame this question in this manner, "Why does cubic unit of cold water have more molecules than same cubic unit of hot water" This is so because heat causes movement in molecules and malkes them move apart. Hence the hotter the water, the further apart the molecules. Therefore, cold water has more molecules than hot water of same unit.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Why does ice have a difference difference density than liquid water?
It has a different amount of space between molecules.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state

Do honey molecules interact more stronger than water molecules?
No, honey molecules do not interact more strongly than water molecules. Honey is a syrupy liquid that is composed mostly of water molecules, along with other compounds such as sugars. The intermolecular forces between water molecules, such as hydrogen bonding, are generally stronger than the forces between honey molecules, making water more cohesive and having a higher surface tension than honey.
What happens when the number of water molecules is greater in one area than another area?
If the number of water molecules is greater in one area than another, water will flow from the area with more water molecules to the area with fewer water molecules until equilibrium is reached. This process is known as osmosis, which helps to balance the concentration of water across different areas.
Is it always true that the molecules of dense liquid are heavier than the molecules of lighter molecules?
NO. Water has a density greater than gasoline, but gasoline, octane anyway, has a greater molecular mass than water molecules.
Are the molecules in ice packed more tightly than the molecules in water?
Compared to a solid object's molecules no. Unless the water is ice. Water molecules are more compact than gaseous molecules.
Is neon less or more dense than water?
At room temperature, neon, which is an inert gas, is far and away less dense than water. Water, as you know, is a liquid at room temperature, and neon is never found in nature on earth as anything but a gas. A link can be found below.
Which 1 has more molecules 9 g of water or 9 g of sugar?
9g of water

Does ice molecules has less mass than water molecules?
no it has more
