The diagram shows a syringe containing air. The end of the syringe has been sealed. The volume of air is 150cm^3, at a pressure of 100kN/m^2 (100kPa). a). Explain, in terms of the movement of molecules, how the air exerts a pressure on the inside surface of the syringe.

b). A force is now applied to the piston. This compresses the air to 120cm^3. The temperature remains constant. What is the pressure of the air now?

150cm^3, at a pressure of 100kN/m^2 (100kPa).

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
