What is the force exerted by a gas against the walls of container?
The force of gas particles against the walls of a container is called pressure.
What is the force exerted on the side of the container by a single molecule?
The pressure in the container is the magnitude of the normal force F on a wall divided by the surface area A of the wall. By Newton’s third law, the average force that the molecule exerts on the wall is Fwall = mvx2/L, it is proportional to the square of the speed of the molecule or its kinetic energy.
How do you go from momentum to force?
They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.
How do you find the force exerted by a gas?
The pressure (P) the gas exerts on the piston is equal to the force (F) with which it pushes up on the piston divided by the surface area (A) of the piston. Thus, the force exerted by the gas is equal to the product of its pressure times the surface area of the piston.
Which of the following refers to the force exerted by the molecules on the wall of the container as a result of constant collisions of molecules?
Define pressure.
What is exerted when atoms collide with the walls of their container?
The pressure of a gas results from collisions between the gas particles and the walls of the container. Each time a gas particle hits the wall, it exerts a force on the wall.
What is the force of momentum?
Momentum is the force that exists in a moving object. The momentum force of a moving object is calculated by multiplying its mass (weight) by its velocity (speed). rock going at 10 mph has much more momentum force than a 3-lb. ball going at the same speed.
Which of the following affects the average force exerted by an ideal gas on the wall of its container?
pressure
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
What is exerted when molecules collide with the walls of their container?
The pressure exerted by a gas in a container results from collisions between the gas molecules and the container walls. Gas molecules exert no attractive or repulsive forces on each other or the container walls; therefore, their collisions are elastic (do not involve a loss of energy).
What are the 5 assumptions of the kinetic theory of gases?
The five main postulates of the KMT are as follows: (1) the particles in a gas are in constant, random motion, (2) the combined volume of the particles is negligible, (3) the particles exert no forces on one another, (4) any collisions between the particles are completely elastic, and (5) the average kinetic energy of …
Which statement is correct when gas molecules collide with the walls of a container?
Statement 1 : In the kinetic theory of gases, collisions between gas particles and the walls of the container are considered elastic. Statement 2 : Gas molecules are considered point like, volume less particles with no inter molecular forces and in constant, random motion.
