Answer:
Energy added to cold water, E1
E1 = m•Cp•ΔT = 6 x 4.187x(42-20) = 6x4.187x22
Energy lost by hot water, E2:
E2 = X(CpΔT) = X x 4.187 x (75-42) =X x 4.187 x 33
So, since E1 = E2
6x4.187x22 = X x 4.187 x 33
X = 6x22/33 = 4.0kg
So the mass of the hot water added to the 6kg of cold water is 4.0kg

 <u>Answer:</u>
Nature consists of both the organism and the environment. The relationship between them are intertwined. Organisms are mainly divided into three
a) The producers 
b) The consumers 
c) Decomposers
These three organisms are interlinked with each other. Without them there is no existence of the environment. The producers produce the food, the consumers consume them and the decomposers decompose and release it in the form of energy. In each cycle energy is released and absorbed. The balance in the environment is maintained by the food pyramid. 
 
        
             
        
        
        
Answer:
Evaporation
Explanation:
*-*-*-*-**-*-*-*-*-*-*
When the sun gets hot, water from any lakes, oceans, rivers, or any part with a large body of water evaporates. 
This means that water turns into a gas form called "water vapor" that rises into the atmosphere.
