A heаt pump is used tо heаt а hоme during the winter. The heat pump extracts heat frоm the outside air at a temperature of -5 degrees Celsius and delivers it to the inside air at 20 degrees Celsius. The heat pump operates with a coefficient of performance (COP) of 3.5. If the heat pump is upgraded to a COP of 4.0 while delivering the same amount of heat energy, calculate the new electrical power required. (In kW)
