Step 6: Determine the change in temperature for the water in each can.

1. Determine the temperature change in the silver can. Subtract the 1 -minute mark temperature reading from the 19-minute mark temperature reading.

1. Determine the temperature change in the black can. Subtract the 2-minute mark temperature reading from the 20-minute mark temperature reading.
