When an explosive like TNT is detonated, a mixture of gases at high temperature is created. Suppose that gas X has a pressure of 50.0 atm, gas Y has a pressure of 20.0 atm, and gas Z has a pressure of 10.0 atm at detonation.
A. What is the total pressure in the system when detonated?
B. Once the gas mixture cools, Ptot=2. atm, what is Py at the cooler temperature?
