mmmm enthalpy
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
The specific heat of the substance.
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
Approx 4974 Joules.
314j
The specific heat for aluminum is 0.9 J/g/degree and you use the equation of q = mC∆T.q = (30.0 g)(0.9 J/g/deg)(50 degrees) = 1350 J 0r 1.35 kJ
Most materials, including aluminum, have a thermal conductivity that can vary with temperature. Most measurements are made at specified temperatures. Some use room temperature, about 25 degrees C. The conductivity is easy to find in engineering handbooks or the Web. But is measured in watts/degree K/m. 250 in the case of aluminum.
The number of calories required will depend on the mass of water which is to be heated.

To raise the temperature of one cc of water requires i calorie of heat . you did not specify the volume.
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.
