Answer:
Explanation:
Thermal Power Plants generate electricity by converting heat into electricity, essentially by burning a fuel. ... A coal power plant works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine

Answer : The molar concentration of ethanol in the undiluted cognac is 8.44 M
Explanation :
Using neutralization law,
where,
= molar concentration of undiluted cognac = ?
= molar concentration of diluted cognac = 0.0844 M
= volume of undiluted cognac = 5.00 mL = 0.005 L
= volume of diluted cognac = 0.500 L
Now put all the given values in the above law, we get molar concentration of ethanol in the undiluted cognac.
Therefore, the molar concentration of ethanol in the undiluted cognac is 8.44 M
Answer:
Final T = 298.7K
Explanation:
In this problem, the heat given for the iron is equal to the heat that water absorbs. Using the equation:
Q = C*m*ΔT
<em>Where Q is heat given = 270000J</em>
<em>C is specific heat of substance = 0.385J/gK</em>
<em>m is mass of iron = 1000g</em>
<em>ΔT is change in temperature = Initial temperature - Final temperature.</em>
<em />
270000J = 0.385J/gK*1000g*(1000K-Final temperature)
701.3J/K = 1000K - Final T
<h3>Final T = 298.7K</h3>
