Q. The triple point for carbondioxide is at about -56.7 C and about 5 atm, pressure. It means that (Solved)
1. Mass transfer at triple point is maximum
2. When CO2 is exposed to a below 5 atmosphere pressure only solid and liquid phase exist together
3. Above 56.7 C CO2 exists only as a liquid
4. Below 57.7 C CO2 exists only in liquid form
5. When solid CO2 is exposed to 1 atm pressure it begins to change directly to gas
- e. When solid CO2 is exposed to 1 atm pressure it begins to change directly to gas
