To compare the efficiency of a microwave with the efficiency of an electric kettle, Joey placed 500 mL of water into each. Joey's teacher helped her calculate the energy required to boil the water, which was 168 kJ. The kettle, which wad had a power rating of 1.5 kW, took 132 s to boil the water. The microwave had a power rating of 1.2 kW and took 280 s to boil the water. Which is more efficient?
