A piece of solid CO2 initially at –78 °C is placed in a small plastic container, which is then seale — States of Matter Chemistry Question

A piece of solid CO₂ initially at –78 °C is placed in a small plastic container, which is then sealed and allowed to warm up in a room whose temperature is 22 °C. Ultimately the plastic container explodes, ending any further observations. Which statement best describes the possibility of observing liquid CO₂ before the container explodes? (The phase diagram of CO₂ is shown below.)
