✔ 最佳答案
Pressure is proportional to temperature when volume is constantAt the triple point of water, temperature = 0 °C = 273 K
Since CO2 solidifies at -78 °C = 195 K,
New pressure = 1.35*195/273 = 0.964 atm

Triple point of water = 0'C = 273 K
Freezing point of CO2 = -78'C = 195 K
Applying Pressure Law (i.e. pressure proportional to temperature),
The required pressure = 1.35 x 195/273 = 0.964 atm
Freezing point of CO2 = -78'C = 195 K
Applying Pressure Law (i.e. pressure proportional to temperature),
The required pressure = 1.35 x 195/273 = 0.964 atm
