The sublimation temperature of solid CO2 is -78.5°C at 1 bar pressure. At what minimum pressure must CO2(g) be stored in a fire extinguisher at 25°C such that "snow" (solid CO2) is produced when the gas is released to atmospheric (~1 bar) pressure? Assume that the process is isenthalpic and that μJT = 1.1 K/bar and is constant with pressure and temperature (in reality it isn't, this is an approximation)

The sublimation temperature of solid CO2 is -78.5°C at 1 bar pressure. At what
minimum pressure must CO2(g) be stored in a fire extinguisher at 25°C such that "snow" (solid
CO2) is produced when the gas is released to atmospheric (~1 bar) pressure? Assume that the
process is isenthalpic and that μJT = 1.1 K/bar and is constant with pressure and temperature
(in reality it isn't, this is an approximation)
