Answer:
$Q=4450.74\ J$

Step-by-step explanation:

Given

mass of tin
m=100 gm

Also we know that

specific heat of tin
$c_(tin)=0.21 J/gm-^(\circ)C$

Melting Point of Tin
$T=231.94^(\circ)C$

Heat required to raise the temperature of 100 gm tin is given by

$Q=mc\Delta T$

where
$Q=heat\ added$

$c=specific\ heat\ of\ tin$

$\Delta T=change\ in\ temperature$

Q=100* 0.21* (231.94-20)

$Q=4450.74\ J$
