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>
