Answer; 
Open system; can exchange both matter and energy; An example is a living organism such as human being, we actively interact with environment, which results in changes  to both the environment and human being, for instance we eat to acquire energy.
Closed system; can exchange energy but not matter; An example is a saucepan, t<span>he saucepan allows energy transfer as the saucepan heats up and heats the contents inside it, putting a lid on it, prevents matter from entering and becomes a closed system.</span>
Isolated system; Can exchange neither energy nor matter. For example is a thermos. if tea is poured into a thermos or an insulated container there is no exchange of heat or matter. 
        
             
        
        
        
Heat transfer means heat energy is transferred from on object or a body to another. This causes change in many factors, and temperature is one of such factors. If the temperature increases, it means heating is taking place and if temperature decreases it means cooling is taking place.
If Tfinal is more than Tinitial, it means the object has gained some amount of heat energy. Therefore, heating is taking place.
If Tfinal is less that Tinitial, it means the object has lost some heat energy and cooling is taking place.
