Question

The specific heat of silver is 0.235 j/

Answer 1

The energy needed the raise the temperature of the block of silver is given by:
$Q=mC_s \Delta T$
where m is the mass of the block, Cs the specific heat capacity of silver and $\Delta T$ its increase in temperature.

Using the numbers of the problem, we find
$Q=(8 g)(0.235 J/gC)(50 C)=94 J$
