Given, #T_1=24+273=297K# And, #beta=7# So,solving the equation ,we get, #T_2=259.875K=259.875-273=-13.125^@C#
WebQuestion: (a) A freezer maintains an interior temperature inside of -26.0°C and has a coefficient of performance of 3.00. The freezer sits in a room with a temperature of 20.0°C. The freezer is able to completely convert 24.0 g of liquid water at 20.0°C to ice at -26.0°C in one minute. WebFeb 15, 2024 · Here’s how you can calculate the Coefficient Of Performance (COP) for a heat pump: COP heat pump = T (hot) / (Thot – Tcold) T (hot) denotes the hot temperature you want during cold weather conditions (95F or 298K). On the contrary, T (cold) indicates cold temperature where your heat pump begins to function (57F/ 287K).
