A thermally isolated container holds 50 mL of water. A 5 ohm resistor, connected to a 10 V power supply, is placed into the water and the circuit is turned on for 5 minutes. During this time heat generated by the resistor is absorbed by the water, which hats up from an initial temperature of 20 degrees Celsius a final temperature of 48.7 degrees Celsius.
1) what is the rate of energy (power)dissipated through the resistor, in Joules per seconds?
2) How much energy is dissipated during the 5 minute interval?
