Answer:

$c=1\ J/g^\circ C$

Step-by-step explanation:

Given that,

Heat required, Q = 8000 J

Mass, m = 400 g

The change in temperature,
$\Delta T = 20^(\circ)$

The heat required due to change in temperature is given by :

$Q=mc\Delta T\\\\c=(Q)/(m\Delta T)\\\\c=(8000 )/(400* 20)\\\\c=1\ J/g^\circ C$

So, the specific heat of the substance is
$1\ J/g^\circ C$
