<p>Do we need to know the exact value on the changes in boiling and melting point? (0.51K and -1.86K respectively)</p>
<p>Does anyone know?</p>
<p>Where’d you get those numbers from? I thought you find them using dT=iKfM and 100+dT=iKbM </p>
<p>For water (0.51K & -1.86K) yeah they expect you to know those two. But not for every single compound.</p>
