We all know that carbon dioxide freezes on temperature -78.5 degrees celsius but i particularly want to know at what pressure does carbon dioxide form solid carbon dioxide also known as frozen ice .
-
The freezing point for any substance depends on the temperature it is subjected to.
-78.5°C is freezing point for CO2 at 1 atm pressure ( generally mentioned since its at normal pressure)
And its -56.65°C at 5.11 atm ( its triple point)
You can try searching for CO2 phase diagram to get more details

At temperatures below −56.4 °C (−69.5 °F) and pressures below 5.13 atm (the triple point), CO2 changes from a solid to a gas with no intervening liquid form, through a process called sublimation.

You mean known as dry ice?
CO2 will freeze at -78.5 C at standard atmospheric temperature. At any other pressure besides atmospheric, it will freeze at a temperature different from -78.5 C
