3) A gas that has a volume of 28 liters, a temperature of 318K, and an unknown pressure has its volume increased to 34 Liters and its temperature decreased to 308K. If I measure the pressure after the change (P2) to be 2.0 atm what was the original pressure of the gas?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
