A student knows that the sublimation point of carbon dioxide (CO2) is -78.5°C. That is, at this temperature, solid carbon dioxide will change state directly from a solid to a gas. The student is asked to predict the temperature at which gaseous carbon dioxide will change directly from a gas to a solid. Which prediction will be
supported by experimental evidence?

A. The change of state will occur at a temperature greater than -78.5°C.

B. The change of state will occur at a temperature less than -78.5°C.

C. The change of state will occur at a temperature of -78.5°C.

D. The change of state will occur at a temperature of 0°C.
