What is the velocity of hydrogen?
The velocity of hydrogen can vary depending on the specific conditions, such as temperature and pressure. In a broad sense, hydrogen molecules at room temperature have an average velocity of about 1.8 km/s.
Do molecules have the lowest average kinetic energy in a plasma?
No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
The average kinetic energy of gas is directly proportional to the temperature. So at 40K, the fraction of the average kinetic energy of hydrogen gas compared to that at 100K would be (40K)/(100K) = 0.4 or 40%.
What substance has greater average kinetic energy at 10 degree celsius?
At 10 degrees Celsius, gas molecules generally have greater average kinetic energy compared to liquid molecules. This is because gas molecules are in a higher energy state due to their increased vibrational and translational motion.
Why do molecules of gas travel faster than liquids?
Molecules of gas have higher average kinetic energy compared to molecules in liquids, which allows them to move at faster speeds. Additionally, gases have greater spacing between molecules and weaker intermolecular forces, leading to more frequent collisions and higher velocities in gases compared to liquids.
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.
Why does ammonia gas diffused faster than hydrogen chloride gas?
Ammonia gas diffuses faster than hydrogen chloride gas because ammonia molecules are smaller and lighter, leading to higher average speeds and quicker diffusion rates. Additionally, ammonia molecules have fewer intermolecular forces compared to hydrogen chloride molecules, allowing them to move more freely and diffuse faster.
What is the velocity of hydrogen?
The velocity of hydrogen can vary depending on the specific conditions, such as temperature and pressure. In a broad sense, hydrogen molecules at room temperature have an average velocity of about 1.8 km/s.
Why do oxygen molecules move slowly than hydrogen molecules at the same temperature?
Two gasses at the same temperature have the same amount of average kinetic energy per molecule. Since an oxygen molecule has about 16 times the mass of a hydrogen molecule, it must move faster than a hydrogen molecule with the same kinetic energy. This is based on the equation KE=1/2MV2
Which has a higher boiling point between H2O or H2Se?
Water has a higher boiling point than hydrogen selenide, because the strong hydrogen bonding of water gives it a higher "effective" molecular weight than hydrogen selenide, the unit that must be vaporized on boiling consisting on average of several water molecules rather than only one. The selenide, in contrast, forms only weak hydrogen bonds; therefore, its average "effective" molecular weight in essentially that of a single molecule.
Do molecules have the lowest average kinetic energy in a plasma?
No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.
Which gas from among CO2 CH4 H2 will diffuse the fastest and why give the reason?
Hydrogen (H2) will diffuse the fastest because it has the smallest molecular weight, which corresponds to higher average speeds of the gas particles at a given temperature. This allows hydrogen molecules to move more quickly through a medium compared to the heavier carbon dioxide (CO2) and methane (CH4) molecules.
Does water expand or contract when frozen?
expands because hydrogen bond operates the molecules and increase the average distance between molecules
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
The average kinetic energy of gas is directly proportional to the temperature. So at 40K, the fraction of the average kinetic energy of hydrogen gas compared to that at 100K would be (40K)/(100K) = 0.4 or 40%.
What is the average speed of Hydrogen molecules?
At what temperature? Average speed is the square root of - 8 times the gas constant, times the absolute temperature, divided by pi times the mass of the molecule.
What substance has greater average kinetic energy at 10 degree celsius?
At 10 degrees Celsius, gas molecules generally have greater average kinetic energy compared to liquid molecules. This is because gas molecules are in a higher energy state due to their increased vibrational and translational motion.
Why hydrogen gas will diffuse fastest?
Hydrogen gas is the lightest element, which means it has the smallest molecular size and mass. This leads to it having higher average velocity at a given temperature compared to other gases, allowing it to diffuse more rapidly. Additionally, hydrogen gas molecules have weaker intermolecular forces, which further promotes faster diffusion.
