Question

Find the specific heat of sikver in J/g C if 38.5 cal is required to heat 25.0g of silver from 31.5 C to 58.7 C (1cal=4.184 J)

Answer 1

Answer:

The specific heat of silver is 0.236 J/g-C.

Explanation:

Mass of silver is 25 g.

The temperature changes from 31.5° C to 58.7° C.

Heat required is 25 g

It is required to find the specific heat of silver. The heat required by silver is given by :

$Q=mc\Delta T$

c is specific heat of silver

$c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{38.5 \times 4.184}{25(58.7-31.5)}\\\\c=0.236\ J/g-C$

So, the specific heat of silver is 0.236 J/g-C.
