    Base your answers to questions 11 on the information below and on your knowledge of chemistry.

    Carbon dioxide, CO2, changes from the solid phase to the gas phase at 1 atm and 194.5 K. In the solid phase, CO2 is often called dry ice. When dry ice sublimes in air at 298 K, the water vapor in the air can condense, forming a fog of small water droplets. This fog is often used for special effects at concerts and in movie-making.

    11

    At 1 atm and 190. K, compare the amount of thermal energy in a 1.0-kilogram block of dry ice to the amount of thermal energy in a 2.0-kilogram block of dry ice.

    Allow 1 credit. Acceptable responses include, but are not limited to:

    • The block of dry ice with less mass contains less thermal energy.

    • There is more thermal energy in the 2.0-kg block.
