The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
How do the molecules in an ice cube at 0 degree celsius compare with molecules that are at 20 degree celsius?
The molecules in an ice cube at 0 degrees Celsius move more slowly and are more orderly arranged in a solid structure than the molecules in a substance at 20 degrees Celsius, which are moving quicker and have more kinetic energy. The increased kinetic energy at 20 degrees Celsius results in the substance being in a liquid state instead of a solid state like the ice cube.
Does water or methane have a stronger force of attraction between its particles?
Water is a polar molecule whereas methane is a non-polar molecule.The intra- molecular force in water molecule is much stronger compared top the intra- molecular force between a carbon and a hydrogen in methane.Water molecule have hydrogen bonding as its intra molecular force.Hydrogen bonding is the strongest, then comes dipole-dipole and the least strong is the London dispersion force.The molecular bonding of water is higher than that of methane (binding energy), and the intermolecular bonding of water is higher than that of methane (boiling point).
How much methane equals to 1 kg of LPG?
1 kg of LPG is equivalent to around 1.36 cubic meters of methane.
Why is the boiling point of methane much lower than the boiling point of hydrochloric acid?
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
How much is 2 meter cube equal to centimeter cube?
100,000 = 1 cubic meter 200,000 = 2cubic meters
If the size of 1 bacteria is 1 micrometer how much will fit in a centimeter cube?
== == 9
HOW MUCH IS 30 x 20 x 2 IN CENTIMETERS?
The value equals to 1200 centimeter cube.
How much is 1 cubic centimeter?
It's the same volume as a cube with all sides 1cm long. 1cm^3 = 1 milliliter

How much a 2.5 cm cube of silver weigh?
One cubic centimeter of silver weights 10.497g so 2.5 cubic centimeters of silver would be 26.2425g.
How many molecules fit in a one centimeter box?
The number of molecules that can fit in a one centimeter box depends on the substance being considered. For example, in a gas like oxygen at room temperature and pressure, approximately 2.5 x 10^19 molecules would fit in a one centimeter cubic box. In contrast, solids or liquids have much denser packing, leading to a significantly higher number of molecules. Therefore, the specific number varies widely based on the material's state and density.
The boiling temperature of water is so much higher than that of methane because water molecules are what?
Water is polar and is strongly hydrogen bonded.
How much density does a ice cube weigh?
The density of ice is approximately 0.92 grams per cubic centimeter. Therefore, the weight of an ice cube would depend on its size and shape. A standard ice cube that is 2 centimeters on each side would weigh around 3.7 grams.
Which type of bonding explains why methanol has a much higher boiling point than methane?
Methanol has a much higher boiling point than methane primarily due to hydrogen bonding. In methanol (CH₃OH), the presence of the hydroxyl (-OH) group allows for strong hydrogen bonds between methanol molecules. In contrast, methane (CH₄) has only weak van der Waals forces (dispersion forces) between its molecules. This significant difference in intermolecular forces results in methanol requiring more energy to boil compared to methane.
How much centimeter is a decimetre?
1 decimeter = 10 centimeter
Which is bigger centimeter or megameter?
A megameter is much larger than a centimeter.
