Calorimetry can be used to determine the specific heat capacity of an unknown substance. True

False

TRUE

Explanation:

Main job of calorimeter is to measure energy changes or determine specific heat capacity of different substances. Specific heat is an intensive property (like density, color, etc.) that does not depend on the amount of a substance present. This allows substances to be identified using their specific heat. Thus, calorimeter comes very handy in determining the specfic heat of unknown substance.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
