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.
Oh, that's a hot topic! Before using the graph to infer about the temperature rise of a 10.0-g sample of iron, your friend should ask: "Hey, Mr. Graph, are there any limitations or assumptions that I should be aware of?" After all, graphs can sometimes be sneaky and hide important information behind those fancy lines and numbers.
Before using the graph in that way, your friend should ask the following question:
1. Is the specific heat capacity of iron the same as that of aluminum, copper, and tin?
This is an important question because the specific heat capacity determines how much the temperature of a substance will rise for a given amount of heat energy input. If the specific heat capacity of iron is different from the other substances, then the calculation based on the graph would not be accurate.
Before using the graph to infer the temperature rise of a 10.0-g sample of iron, your friend should ask the following questions:
1. Is the heating process the same for all substances?
This is important to understand because the graph only provides information about the temperature rise for specific substances, such as aluminum, iron, copper, and tin. It is essential to confirm that the heating process for iron is similar to that of the substances represented in the graph.
2. Does the graph provide a linear relationship?
If the graph is linear, it means that the temperature rise is directly proportional to the mass of the substance. In that case, your friend can use the graph to make accurate inferences. However, if the graph does not follow a linear relationship, estimating the temperature rise based on the graph alone could be less reliable.
3. Are there any limitations or assumptions?
It's crucial to consider any limitations or assumptions made when constructing the graph. For example, the graph may have been created based on specific experimental conditions or assumptions about the behavior of the substances. Understanding the context and conditions under which the graph was created will help ensure accurate interpretations.
By considering these questions, your friend can make a more informed decision about whether it is appropriate to use the graph to infer the temperature rise of a 10.0-g sample of iron.
