An electrical heater is used to supply 105.0 J of energy to a 15.0 g sample of aluminum (specific heat is 0.901 J/(goC), originally at 295.0 Kelvin. Determine the final temperature in Kelvin.


Expert Answer

Step 1

The heat supplied to a sample of aluminium is 105 J. The final temperature is calculated as,
