A laboratory technician investigates the physical phase transitions of different pure substances under a constant pressure of $atm1\text{ atm}$ . The observations are recorded in the table below:

Table 1

Substance	State at $−100∘C-100^\circ\text{C}$	State at $25∘C25^\circ\text{C}$	State after cooling back to $−100∘C-100^\circ\text{C}$
Mercury	Solid	Liquid	Solid
Carbon dioxide	Solid	Gas	Solid
Quartz (silica)	Solid	Solid	Solid

What are the correct systematic thermodynamic terms for the phase transitions undergone by the carbon dioxide sample during the heating and cooling stages, respectively?

Heating: Sublimation; Cooling: Condensation

Heating: Vaporisation; Cooling: Freezing

Heating: Sublimation; Cooling: Deposition

Heating: Boiling; Cooling: Deposition
