What is the final pressure inside the hole?
Dry ice has occasionally been used as an "explosive" in mining. A hole is drilled, dry ice and a small amount of gunpowder are placed in the hole, a fuse is added, and the hole is plugged. When lit, the exploding gunpowder rapidly vaporizes the dry ice, building up an immense pressure. Assume that 493 g of dry ice is placed in a cavity with a volume of 0.710 L and the ignited gunpowder heats the CO2 to 710°C.

PV = nRT
P = nRT / V = ((493 g CO2) / (44.0096 g CO2/mol)) x (0.08205746 L atm /K mol) x
(710 + 273K) / (0.710 L) = 1.27 x 10^3 atm
