Answer:

Heat, Q = 262 kJ

Step-by-step explanation:

Given that,

Mass of a sample, m = 750 g

Initial temperature,
$T_i=95^0\ C$

Final temperature,
$T_f=17^0\ C$

The specific heat of the sample,
$c=4.18\ J/g^0 C$

We need to find the amount of heat released. The amount of heat released is given by the formula as follows :

$Q=mc\Delta T\\\\Q=750* 4.48* (17-95)\\\\Q=-262080\ J\\\\Q=-262\ kJ$

So, 262 kJ of heat is released by the sample.
