A pure solid and a pure liquid are definitely a single phase because they are so united, or homogeneous. This leads to a homogeneous mixture also being a single phase.
The option that cannot be considered a single phase is D. a heterogeneous mixture.
H2O- H+ O2-. YES HYDROGEN ARE MADE UP OF HYDROGEN AND OXYGEN ATOMS
Energy released from changing the phase of a
substance from the liquid phase to solid phase can be calculated by using the
latent heat of fusion. The heat of fusion of iron is calculated as follows:
<span>Energy = mL(f)</span>
<span>9840 cal (4184 J / 1 cal) = .200 kg x L(f)</span>
L(f) = 2.06 x10^8 J/kg
<em>Question: </em><em>Which cup has more thermal energy?</em>
<em> A. 2 liter cup of milk</em>
<em> B. 1 liter cup of milk</em>
<em>Answer: A. 2 liter cup of milk</em>
<em />
<em>Explanation:</em>
We have milk in both of the containers. The milk in both containers is the same temperature, so we will have to measure the amount of molecules. The amount of molecules makes it warmer, and if it is warmer, that is more energy. 2 liters have more thermal energy than 1 liter, because it has more molecules.
Our answer is 2 liter cup of milk.
