A 0.5 kg block of aluminum (specific heat capacity = 900 J/kg·°C) is heated from 20°C to 80°C using a 2.0 kg container of water (specific heat capacity = 4186 J/kg·°C) initially at 25°C. Assume no heat is lost to the environment. A 1000 J heat source is applied to the aluminum block. Calculate the temperature increase it causes.

A heat pump is used to heat a home during the winter. The heat pump extracts heat from 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. Calculate the amount of heat extracted from the outside air per second. (In kW)

A heat pump is used to heat a home during the winter. The heat pump extracts heat from 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)
