0.004167 J/g°C is the specific heat of a substance.

Explanation:

$Q=m\times c\times \Delta T$

$Q=m\times c\times (T_{2}-T_1)$

Where:

Q = heat absorbed(positive) or released (negative)

m = Mass of substance

c = specific heat of a substance

T_1 = Initial temperature

T_2 = Final temperature

We have:

m = $1.0\times 10^4 g$

c = ? , T_1=10^oC,T_2=70^oC

Q = $2.5\times 10^3 J$

$2.5\times 10^3 J=1.0\times 10^4 g\times c\times (70^oC-10^oC)$

$c=\frac{2.5\times 10^3 J}{1.0\times 10^4 g\times (70^oC-10^oC)}$

c=0.004167 J/g^oC

0.004167 J/g°C is the specific heat of a substance.
