Answer:
The correct answer is "430 kJ/kg". A further explanation is given below.
Explanation:
The given values are:
T₁ = 400 k
T₂ = 800 k
The average temperature will be:
= 
= 
= 
From table,
At 600 k the 
will be = 1.075
Now,
⇒ The specific enthalpy = 
⇒ 
⇒ 
Answer:
The control in this experiment is the temperature and amount of water.
Explanation:
This is because for it to be a fair test the temperature and the amount of water need to be the same so they would both evaporate if there was no air being blown. Ask me if you would like me to elaborate on this.
