Answer :
Heating takes place during the process of Evaporation, Melting, Sublimation.
Cooling takes place during the process of Freezing, Condensation, Deposition.
Explanation :
Heating : It means thermal energy releases.
Cooling : It means thermal energy absorbs.
Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.
Melting : It is a process in which a solid changes into liquid phase by providing heat.
Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.
Freezing : It is a process in which a liquid transform into a solid phase at low temperature.
Condensation : It is a process in which a water vapor(gas) changes into liquid state at low temperature.
Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.
They help us understand the concept of evolution and they help us understand what our earth was like before and after pangea or the great continental drift

Answer:
That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 10 23 atoms, molecules, or formula units of that substance. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.
