The heat capacity for aluminum = 0.89 J/(oC*grams)
The heat capacity for water = 4.18
m water = 200 grams
t water = 1 degree C
t aluminum = 10 degrees C
Formula
Thermal energy = m * c * t
Solution
Water
Energy = m * c * t
Energy = 200 * 4.18 * 1
Energy = 836 Joules
Aluminum
Energy = mc t
Energy =100 * 0.89 * 10
Energy = 890
Answer Aluminum has the higher Thermal Energy
Note this is a very tricky question. Usually delta t is given in terms of a change in temperature or heat transfer. This question assumes the substance is at a constant temperature at a short time interval so delta t is a constant amount for that time interval. Be very careful when you think about this, because the laws of thermo dynamics begin to act almost immediately.
