The specific heat of the metal is 0.23J/g^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed= 2.50kJ=2500J

m= mass of substance = 135 g

c = specific heat capacity = ?

Initial temperature = T_i = 19.5°C

Final temperature = T_f =100.0°C

Change in temperature , $\Delta T=T_f-T_i=(100-19.5)^0C=80.5^0C$

Putting in the values, we get:

$2500=135\times c\times 80.5^0C$

c=0.23J/g^0C

The specific heat of the metal is 0.23J/g^0C
