Q= c m T (T is the change in time)

C= Q/(mT)
= 266/(0.015kg x 25)
C=709.33 J/kg.C

Answer:


c=0.709\ J/g\ ^(\circ) C

Step-by-step explanation:

Given that,

Heat required to raise the temperature, Q = 266 J

Mass, m = 15 g

Temperature,
\Delta T=25^(\circ)\ C

To find,

The specific heat of graphite.

Solution,

The formula for the specific heat is given by :


Q=mc\Delta T


c=(Q)/(m\Delta T)


c=(266\ J)/(15* 25)


c=0.709\ J/g\ ^(\circ) C

So, the specific heat capacity of graphite is
0.709\ J/g\ ^(\circ) C. Hence, this is the required solution.
