q = m(DT)Cp
Use the above formula to solve the problems below.
Remember to list the known and unknowns.
| 1. Determine the specific heat of a certain
metal if a 450 gram sample of it loses 34 500 Joules of heat as its temperature drops by
97 oC.
|
| 2. 4786 Joules of heat are transferred to a 89.0 gram sample of an
unknown material, with an initial temperature of 23.0 oC.
What is the specific heat of the material if the final temperature is 89.5 oC?
|
| 3. The temperature of a 55 gram sample of a
certain metal drops by 113 oC as it loses 3500 Joules of heat. What is
the specific heat of the metal?
