The cake mix, whose initial temperature is 25°C, will be baked at 120°C in a cylindrical mold. It takes 802 h for the core temperature of the cake to reach 98°C and this time is considered sufficient for baking the cake. Calculate the diameter of the mold in which the cake should be placed. h=68.6 W/m?K, d=840 kg/m³ cp=3400 J/kgK, k=1.2 W/mK, A=3.07

Why is information regarding the specific volume of gases important to the designer of air-conditioning, heating, and refrigeration equipment?

Water melts as temp increases because : - chemical potential of the liquid is lower than that of gas - liquid and solid form eutectic mixture -chemical potential of the liquid and solid become equal
