At what temperature will the r.m.s velocity of the hydrogen molecules be doubled of its value at N.T.P.?
The root mean square (rms) velocity of gas molecules is directly proportional to the square root of temperature. To double the rms velocity from its value at standard temperature and pressure (STP), the temperature must be increased by a factor of 4. Therefore, the temperature needed would be 4 times the temperature at STP, which is approximately 293 K.
What is the velocity of hydrogen at 298 K?
The average velocity of hydrogen molecules at 298 K can be calculated using the root mean square velocity formula, v = √(3kT/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a hydrogen molecule. The average velocity of hydrogen at 298 K would be around 1926 m/s.
If you are heating an Oxygen Hydrogen gas do both of the elements molecules speed up at the same rate?
No, the temperature of a gas is a measurement of its kinetic energy and Kinetic energy is dependent on mass E=1/2 m v2 Since O2 has 16 times the mass of H2 its velocity for the same energy has to be less.
What molecules move faster hot gas or cold gas molecules?
Hydrogen atoms have a greater velocity than oxygen atoms when both elements are submitted to identical conditions of temperature and pressure. For your results to be exact, there must be an identical number of moles for each type of atom (e.g. 3 mol of H2 and 3 mol of O2).
What effects does temperature have on pressure in a closed container?
Well the temperature of a gas in a container is directly proportional to the pressure of the gas & according to the kinetic theory of gases (viewing gases as made of particles which are in constant random motion) the change in pressure with respect to temperature is given by 2mvx where m is mass and vx the x-coordinate of the initial velocity of the particle. (looking at it as the molecules are colliding with the walls of the container along an axis, x in this case). this proportionality is the basis (implicitly) of Charles's law, Gay-Lussac's law and Boyle's law.
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 all gasses exert pressure in terms of KMT?
Pressure is the effect of collisions with molecules. KMT -- molecules have kinetic energy due to their temperature which imparts more velocity, hence kinetic energy, to the molecules. All gases have KE due to temperature. IF absolute zero was ever achieved there would be no kinetic energy in the molecules, no molecular motion, no collisions, no pressure.
What is the theory that describes the relationships of pressure volume temperature velocity frequency and force of collisions among gas molecules?
The Kinetic Molecular Theory describes the relationships between pressure, volume, temperature, velocity, frequency, and force of collisions among gas molecules. It states that gas molecules are in constant motion and collide with each other and their container walls, leading to the macroscopic properties of gases.
How does temperature effect air pressure and air mass?
When gas molecules are heated, the molecules move more quickly, and the increased velocity causes more collisions. As a result, more force is exerted on each molecule and air pressure increases. Temperature affects air pressure at different altitudes due to a disparity in air density.
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
The condition you are referring to is called temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, such as air. When the average velocity of atmospheric molecules is not zero, it indicates that the substance has a non-zero temperature.
What is the pressure of gas caused by?
Gas pressure is caused by gas molecules zipping around and bumping into things. These molecules have kinetic energy defined a 1/2 the mass times the velocity squared. Increasing temperature increases the speed that the molecules zip around - so the pressure increases (hot soda can for example has more pressure than a cold one).
Why does an increase in temperature increase the volume of a balloon?
This requires one simple equation and then a further understanding of it. PV=nRT where P is pressure, V is volume, T is temperature, n is the number of molecule, R is some constant. From this we can easily see that an increase in temperature does in fact cause an increase in volume. To see why lets think about what temperature is. Temperature is a measure of average kinetic energy. So an increase in temperature increases the average kinetic energy. An increase in average kinetic energy means that average velocity must be increased (K.E = .5(mv^2)). More velocity means that the molecules in the balloon are flying faster, and since pressure is the same, the molecules spread out more, which must increase the volume.
Scientific notation of velocity of sound?
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
What are the factors that affect viscosity?
Viscosity is affected by temperature, where an increase in temperature typically decreases viscosity by reducing the attractive forces between molecules. The type and size of molecules also play a role, with larger molecules or molecules with strong intermolecular forces typically resulting in higher viscosity. Pressure can also have a minor impact on viscosity, with higher pressures generally leading to a slight increase in viscosity.
