Relate the pressure of a gas to its concentration of particles. A) Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.
B) Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles
C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particlees.
D) Pressure will accelerate a gas, extending its volume and allowinq a smaller density and concentration of particles.​

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
