Solid carbon dioxide (CO 2 ) can undergo sublimation to form gaseous CO 2 .Which of the following statements is true?

The motion of molecules in the solid phase is much more restricted than in the gas phase due to the fixed positions of the molecules in a solid, which contrasts with the free movement of molecules in a gas.
