Chapter 12, Problem 12.31(choose chapter or problem)
Use Figure 12.10, p. 466, to answer the following: (a) Carbon dioxide is sold in steel cylinders under pressures of approximately 20 atm. Is there liquid CO2 in the cylinder at room temperature (208C)? At 408C? At 2408C? At 21208C? (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?
