To test the effectiveness of a gunpowder mixture, 1 gram was exploded under controlled STP conditions, and the reaction chamber was found to expand to 310 cm3. What volume would these gases occupy at the temperature produced by an uncontrolled explosion (2,200°C) and 2.1 atmospheres of pressure?

Question

cuanchi · Answer

P1V1/T1=P2V2/T2  => V2 = (P1V1T2)/(T1P2)

convert the T2 to kelvin
2200°C + 273 = ???

P1= 1atm
P2= 2.1 atm
T1= 273
T2= 2200 + 273= 
V1= 310cm3
