12 (a) Describe how you can obtain the integrated form of the Clapeyron equation as below. State any assumptions you have to make. $P_2 \approx P_1 + \frac{\Delta_{fus}H}{\Delta_{fus}V} \cdot \frac{(T_2 - T_1)}{T_1}$ (b) The heat of fusion ($\Delta_{fus}H$) of Hg at its normal melting point ($-38.9^\circ C$) is 2.82 cal$\cdot g^{-1}$. The densities of Hg(s) and Hg(l) at $-38.9^\circ C$ and 1 atm are 14.193 and 13.690 g$\cdot cm^{-3}$, respectively. Estimate the melting point of Hg at 100 atm using the result in (a). Ans 234.8 K or $-38.4^\circ C$

1. Zim aliens are highly social and love to talk with each other. However certain Zims can only hear communication at low frequencies. Others can only hear at high frequencies. Upon a visit to the planet, a geneticist did a phenotype count of 1000 Zims. She found 592 Zims that heard only low frequency and 418 that only heard at high frequency. However, she noted that all of the high frequency Zims lived in the mountains while the low frequency ones lived in the valley. Make a hypothesis about the mode of inheritance and then describe what is happening at a molecular level.
