Answer:

Specific heat capacity of the copper is given as

[tex]s = 0.39 J/g ^oC[/tex]

Explanation:

As we know that the heat required to raise the temperature of the given substance is given as

[tex]Q = ms\Delta T[/tex]

here we know that

[tex]Q = 117 J[/tex]

mass of the given part is

[tex]m = 75 g[/tex]

change in temperature due to heat supply is

[tex]\Delta T = 24 - 20 = 4^oC[/tex]

now we have

[tex]117 = 75 (s)(4)[/tex]

[tex]s = 0.39 J/g ^oC[/tex]
