When ${\mathrm{CO}}_2$ under high pressure is released from a fire extinguisher, particles of solid ${\mathrm{CO}}_2$ are formed despite the low sublimation temperature $\left(-{77}^{\circ }\mathrm{C}\right)$ of ${\mathrm{CO}}_2$ at 1.0 atm. It is :

Despite having a low sublimation temperature $\left(-{77}^{\circ }\mathrm{C}\right)$ at 1.0atm, ${\mathrm{CO}}_2$ is released under high pressure from a fire extinguisher, resulting in the formation of solid ${\mathrm{CO}}_2$  particles. This is because the gas works to cool the surrounding air by pushing the atmosphere backwards using its own energy (KE).
