Q:What happens to the pressure of particles in the container when it is heated.explain.
Q:A pressure of 2200Kpa is exerted by the particles in the container on the wall of area 25cm2. find the force exerted by the particle.
1. Pressure goes up with T. Molecules move faster, collide more often with the wall and have more momentum.
2. Force = pressure x area
For force in newtons, pressure must be in Pascals and are in m^2.
2200*10^3 Pa x 25*10^-4 m^2 = ___
