An electronic device is dissipating 25 W. It has a mass of 20g and a specific heat of 850 J/(kg^oC). The device is lightly used, and it is on for 5 minutes and then off for several hours, during which time it cools to ambient temperature of 25^oC.

Determine the amount of work added to the device within its 5 minute operating period. Remember to show all your work.
Determine the highest possible temperature of the device at the end of the 5 minute operating period.
