One cast iron pan has a mass of 2.26kg and a second cast iron pan has a mass of 3.54kg. Which of the following statements are true? (SELECT ALL THAT APPLY)
-The two pans will have the same specific heat capacity.
-The two pans will have the same heat capacity.
-The heat capacity of the larger pan will be greater than the heat capacity of the smaller pan.
-The heat capacity of the larger pan will be less than the heat capacity of the smaller pan.
-The specific heat capacity of the larger pan will be greater than the specific heat capacity of the smaller pan.
Homework Answers
Specific heat capacity is defined as heat required to raise temperature of 1 g of substance by 1 oC.
This is defined for only 1 gram and hence it do not depend on mass.
Option 1 is correct and option 5 is wrong.
Heat capacity = mass * specific heat capacity
Since specific heat capacity is same for both, the one with greater mass will have greater specific heat capacity.
So, the heat capacity of larger pan is greater
Option 3 is true and option 2 and 4 are wrong
Answer: option 1 and 3

It is a well-known fact that water has a higher specific heat capacity than iron. Now, consider equal masses of water and iron that are initially in thermal equilibrium. The same amount of heat, 30. calories, is added to each. Which statement is true? They are no longer in thermal equilibrium; the iron is warmer. They remain in thermal equilibrium. They are no longer in thermal equilibrium; the water is warmer. It is impossible to say without knowing the exact...
