Answer:
Greywater. 
Explanation:
Greywater is also known as sullage and it can be defined as any form of gently used wastewater derived from sources within a residential or office building such as showers, washing machines, bathroom sinks, bathroom tub, etc. 
Generally, greywater or sullage is completely free of fecal materials (faeces) because it is independent from all toilet activities. However, greywater is not clean for direct use because it usually contains food particles, dirt, oil from dishes, hair, etc.
In this scenario, Anna makes arrangements to reuse waste water that has been used in sinks and showers. Greywater is a term which refers to the waste water that Anna reuses to conserve resources. 
Therefore, Anna reuses greywater to conserve resources.
 
        
             
        
        
        
Answer:
18 kJ
Explanation:
Given:
Initial volume of air = 0.05 m³
Initial pressure = 60 kPa
Final volume = 0.2 m³
Final pressure = 180 kPa
Now, 
the Work done by air will be calculated as:
Work Done = Average pressure × Change in volume
thus, 
Average pressure = 
  = 120 kPa
and, 
Change in volume = Final volume - Initial Volume = 0.2 - 0.05 = 0.15 m³
Therefore, 
the work done = 120 × 0.15 = 18 kJ
