Answer:
Oxygen cycle
Explanation:
The components of the reservoirs of oxygen that are exchange in our environment is the oxygen cycle 
It suggests the movement of oxygen between the living and non-living parts. 
- The cycle does not account for oxygen that is trapped and cannot be exchanged in nature. 
- Oxygen is important component of the atmosphere. 
- Gaseous exchange between living organisms and atmosphere involves oxygen to a very large extent. 
 
        
             
        
        
        
Answer:
20 J/g
Explanation:
In this question, we are required to determine the latent heat of vaporization
- To answer the question, we need to ask ourselves the questions:
What is latent heat of vaporization?
- It is the amount of heat required to change a substance from its liquid state to gaseous state without change in temperature.
- It is the amount of heat absorbed by a substance as it boils.
How do we calculate the latent heat of vaporization?
- Latent heat is calculated by dividing the amount of heat absorbed by the mass of the substance.
In this case;
- Mass of the substance = 20 g 
- Heat absorbed as the substance boils is 400 J (1000 J - 600 J)
Thus,
Latent heat of vaporization = Quantity of Heat ÷ Mass 
                                              = 400 Joules ÷ 20 g 
                                              = 20 J/g 
Thus, the latent heat of vaporization is 20 J/g
