A chemist places a 100 g cube of each of the metals listed in the table on a separate hot plate. All of the hot plates are identical. Each hot plate is set on medium heat, and all of the cubes have the same initial temperature. Based on the specific heat values in the table, rank the metals in terms of how quickly they will reach the target temperature of 80°C. Use "1" to indicate the fastest and "5" to indicate the slowest.
