Some very hot rocks have a temperature of #240 ^o C# and a specific heat of #240 J/(Kg*K)#. The rocks are bathed in #16 L# of water at #70 ^oC#. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
1 Answer
You need the heat of vaporization to answer the question.
About
Explanation:
The heat of vaporization for water is
Then, let's solve the problem with the formula
(
Let
If
And, if
The heat energy must follow the law of energy conservation law.
Therefore, the mass of rocks is
