Enthalpy is the energy needed for the phase change called vaporization. It is the energy needed to break the bonds of the liquid molecules so that it can be converted to its gaseous form. Therefore, the greater the value of the enthalpy is, the stronger are the bonds of the substance. <em>Therefore, the answer is Aluminum.</em>
Answer:
The answer is
<h2>1.61 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 12.9 g
volume = 8 cm³
The density of the block is
We have the final answer as
<h3>1.61 g/cm³</h3>
