Answer:
yes
Explanation:
new compounds made, a chemical reaction is when a new compound is made.
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.
