Question

24.1 KJ is used to heat a piece of aluminium of mass 250 g. What will the final temperature be if its initial temperature is 15.1°C? The specific heat of aluminium is 0.902 J/g.K.

Answer 1

Let final temperature be $T$ ,

Net heat supplied$=mc\triangle T$

$24.1\ KJ=24100\ J=250\times 0.902\times (T-15.1)$

$T-15.1=106.87\degree C\implies T=121.87\degree C$
