Define Frozen Solid (Moscow Phys-Tech)?
Evaluation how long it will take for a small pond of average depth D=0.5 m to freeze entirely in a very cold winter, when the temperature is forever below the freezing point of water. Take the thermal conductivity of ice to be k=2.2 w/m k, the latent heat of fusion q=3.4.105 J/kg, and the density p=0.9.103kg/m3. Acquire the outside temperature to be a constant T0=263K.
