Answer:
[tex]c=1\ J/g^\circ C[/tex]
Explanation:
Given that,
Heat required, Q = 8000 J
Mass, m = 400 g
The change in temperature, [tex]\Delta T = 20^{\circ}[/tex]
The heat required due to change in temperature is given by :
[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{8000 }{400\times 20}\\\\c=1\ J/g^\circ C[/tex]
So, the specific heat of the substance is [tex]1\ J/g^\circ C[/tex]
