A substance has a heat of vaporization of x1cHvap and heat of fusion of x1cHfus. Express the heat of sublimation in terms of x1cHvap and x1cHfus.
Added by Thomas B.
Step 1
It can be expressed as the sum of the heat of fusion (energy required to change a solid into a liquid) and the heat of vaporization (energy required to change a liquid into a gas). ** Show more…

A substance has a heat of vaporization of $\Delta H_{\text { vap }}$ and a heat of fusion of $\Delta H_{\text { fus. }}$ Express the heat of sublimation in terms of $\Delta H_{\text { vap }}$ and $\Delta H_{\text { fus. }}$
CE Four liquids are at their freezing temperature. Heat is now removed from each of the liquids until it becomes completely solidified. The amount of heat that must be removed, Q, and the mass, $m,$ of each of the liquids are as follows: liquid $\mathrm{A}, Q=33,500 \mathrm{J}, m=0.100 \mathrm{kg} ;$ liquid $\mathrm{B}, \quad Q=166,000 \mathrm{J}$ $m=0.500 \mathrm{kg} ;$ liquid $\mathrm{C}, Q=31,500 \mathrm{J}, m=0.250 \mathrm{kg} ;$ liquid $\mathrm{D},$ $Q=5400 \mathrm{J}, m=0.0500 \mathrm{kg} .$ Rank these liquids in order of increasing latent heat of fusion. Indicate ties where appropriate.
