At what temperature will the r.m.s velocity of the hydrogen molecules be doubled of its value at N.T.P.?
rms speed of certain gas molecule at 27C is found to be 1930m/s.Estimate the gas?
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.
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).
Measurement of average amount of motion of molecules is?
The average amount of motion can be determined by the average speed or velocity of an object. The average speed can be calculated by the total distance divided by the total time. Speed is a scalar quantity. The average velocity can be calculated by the total displacement divided by the total time. Velocity is a vector.
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?
Kinetic theory of gases
At what temperature will the r.m.s velocity of the hydrogen molecules be doubled of its value at N.T.P.?
rms speed of certain gas molecule at 27C is found to be 1930m/s.Estimate the gas?
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 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).
How is the bond between hydrogen atoms represented in each model of a hydrogen molecule?
well it is because the hydrogen molecule = the velocity of molecules in hydrogen which gives you the answer to your question.
Is The earth's atmosphere held down to the surface by gravity?
Yes, and it stays put because the force of the Earth's gravity is stronger than the velocity that air molecules gain from temperature increases. Only the lightest molecules (hydrogen and helium) are lost to space again.
What three things affect the frequency of a sound wave?
Velocity, temperature and pressure.
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.
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
What has the most impact on the speed of sound in seawater?
Any factor which alters the density of the sea water causes a variation in the velocity of sound in seawater. Basically, changes in temperature and salinity will result in changes in density. This can cause large changes in velocity. For example, seawater in the carribean with a temperature of 20C and a salinity of 37ppt might result in a velocity of, say, 1530m/s, whereas seawater in the north sea with a temperature of 3C and a salinity of, say, 31ppt, would result in a velocity of, say, 1480m/s.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of change of the atmospheric pressure, but is really dependent on the temperature.
