Answer: The specific heat of the metal is [tex]0.23J/g^0C[/tex]

Explanation:

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

[tex]Q=m\times c\times \Delta T[/tex]

Q = Heat absorbed=[tex]2.50kJ=2500J[/tex]

m= mass of substance = 135 g

c = specific heat capacity = ?

Initial temperature = [tex]T_i[/tex] = 19.5°C

Final temperature = [tex]T_f[/tex]  =100.0°C

Change in temperature ,[tex]\Delta T=T_f-T_i=(100-19.5)^0C=80.5^0C[/tex]

Putting in the values, we get:

[tex]2500=135\times c\times 80.5^0C[/tex]

[tex]c=0.23J/g^0C[/tex]

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