approximately 20 atm. Is there liquid CO, in the cylinder at roo temperature (~20°C)? At 40°C? At -40°C? At –120°C? (b) Carbon dioxide is also sold as solid chunks, called dry ice, in insulated containers. If the chunks are warmed by leaving them in an open container at room temperature, will they melt? (c) If a container is nearly filled with dry ice and then sealed and warmed to room temperature, will the dry ice melt? (d) If dry ice is compressed at a temperature below its triple point, will it melt?
