The sign's glass absorbed 25466.7 J

<h3>Further explanation</h3>

Given

The temperature of glass : 23.5 °C to 65.5 °C

mass = 905 g

the specific heat capacity = 0.67 J/g °C

Required

Heat absorbed

Solution

Heat absorbed by sign's glass can be formulated :

$\tt Q=m.c.\Delta T$

ΔT=65.5 - 23.5 = 42

$\tt Q=905\times 0.67\times 42\\\\Q=\boxed{\bold{25466.7~J}}$
