Part A)
depends on
Since moment transfer per unit time is nothing but the force and pressure is directly proportional to the force.
mvs2/2 = KT/2
kinetic energy is directly proportional to the temperature of the molecules of the gas.
depends on.
Since kinetic energy is directly proportional to the temperature. hence the speed of particles depends on the temperature.

This problem will review one of the questions in the ideal gas, but with numbers: You have one container of hydrogen, and another container of oxygen. The number of molecules, temperature and volume are the same for both gases. Oxygen is, however, heavier than hydrogen. How does the average kinetic energy of hydrogen compare to oxygen? Hydrogen has LARGER average kinetic energy than oxygen. Hydrogen has THE SAME average kinetic energy as oxygen. Hydrogen has LESS average kinetic energy than...

In lab, we noted that pressure (which should be the same for both gases) is a product of the strength of the collision times the frequency of collisions. The strength is proportional to mv, and the frequency is proportional to v. If we take the mass of hydrogen to be 4 kg and the speed to be 3 m/s (yes - these numbers are ridiculous for a molecule of gas - but the goal here is to focus on concepts...

The rate of diffusion of a particular gas was measured and found to be 50.5 mm/min. Under the same conditions, the rate of diffusion of SF was 18.7 mm/min. What is the molar mass of the unknown gas? What gas might this be? One group of students in an introductory chemistry course is arguing that the pressures of a con- tainer of hydrogen gas and a container of sulfur dioxide gas, under the following conditions, cannot be equal. Both containers...

When a running football player “throws” his right foot down and behind him, as in this sketch, what happens in reaction is: He begins to fall backward. Counter-rotational torque applies. The ground pushes up and forward. The ground exerts no force on him.

Space debris left from old satellites and their launchers is becoming a hazard to other satellites. (a)Calculate the speed in m/s of a satellite in an orbit 860 km above the Earth's surface. (b) Suppose a loose rivet is in an orbit of the same radius that intersects the satellite's orbit at an angle of 90° relative to Earth. What is the velocity in m/s of the rivet relative to the satellite just before striking it? (Enter the magnitude.) (c)...

5. One group of students in an int arguing that the pressu aroup of students in an introductory chemistry course is arguing that the pressures of a con- Chudrogen gas and a container of sulfur dioxide gas, under the following conditions, cannot equal. Both containers are sealed, with equal volume, at the same to that the pressures cannot be equal because a sulfur dioxide molecule has a much larger han diatomic hydrogen, and therefore exerts a much greater force when...
