A friend infers from the graph that the temperature of a 10.0-g sample of iron would rise 110 degrees Celsius. What should she ask before using the graph this way.
(btw the graph depicts that 1 gram of aluminum's temperature rises 5.6 degrees Celsius, 1 gram of iron's temperature rises 11.1 degrees Celsius, 1 gram of copper's temperature rises 13.0 degrees Celsius, and 1 gram of tin's temperature rises 21.9 degrees Celsius)
If the question is to determine the heat absorbed by the metal she must know the specific heat of the iron.
