O The intermolecular forces between solvent-solute are greater than the sum of the solute-solute and solvent- solvent intermolecular forces. O Crystallization is exothermic. O Dissolution is exothermic.

2. A piece of beef steak 7 cm thick will be frozen in the freezer room -40 ° C. This product has a moisture content of 73%, a density of 970 kg / m³, and a thermal conductivity (frozen) of 1.1 W / (m K). freezing time using the Plank equation. This product has an initial freezing temperature of -1.75 ° C, and the movement of air in the freezing room gives a convective heat transfer coefficient of 10 W / (m² K).        t f = Answer    hour.

The plot to the right shows the 1-D steady-state solution to the Pennes bioheat equation with T = 37°C at x = 0 (body core) and T = 43°C at x = 0.01 (body surface). The thermal conductivity is 0.5 W m-l °C-'. This scenario describes some surface tissue thermal conductivity (WI(m°C)) 0.5 blood perfusion rate (1/5) T("C) 43 heating (e.g., laser).
