### Required Information**NOTE:** This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50°C at a rate of 0.024 kg/s and leaves at 750 kPa subcooled by 3°C. The refrigerant enters the compressor at 200 kPa superheated by 4°C.(Take the required values from saturated refrigerant-134a tables.)### Diagram ExplanationThe diagram illustrates a closed-loop heat pump system comprising four main components:1. **Condenser**: The refrigerant enters the condenser at state (2) at 800 kPa and 50°C, where it releases heat (\( \dot{Q}_H \)) to the surroundings, transitioning towards state (3).2. **Expansion Valve**: After exiting the condenser, the refrigerant flows through the expansion valve, decreasing in pressure to 200 kPa and transitioning to a lower temperature at state (4).3. **Evaporator**: Here, the refrigerant absorbs heat (\( \dot{Q}_L \)) from the environment, converting from state (4) back into the gaseous state as it returns to the compressor.4. **Compressor**: The refrigerant enters the compressor superheated by 4°C at 200 kPa at state (1). Work energy (\( W_{\text{in}} \)) is applied to compress the refrigerant back to 800 kPa at state (2).### TaskDetermine the rate of heat supplied to the heated room.**The rate of heat supplied to the heated room is** _______ kW.
