$c_o=1,125 " may be ammonia liquid"$

Explanation:

$Q_o=m_o*c_o*Delta t_o" Heat given by object a mass of 32 g"$
$c_o": specific heat of object"$
$Q_o=32*c_o*120$
$Q_o=3840*c_o$
$Q_w=m_w*c_w*Delta t_w" Heat gained by water"$
$V_=480 m ; m_=480 g ; c_w=1$
$Q_w=480*1*9$
$Q_w=4320 Cal$
$Q_o=Q_w " conversation of energy"$
$3840*c_o=4320$
$c_o=4320/3840$
$c_o=1,125 " may be ammonia liquid"$
