Answer:
Q = 6.56 J
Explanation:
Given thatm
Mass of a sample of gold, m = 8.21 g
The temperature of the sample increase by 6.2°C.
We need to find heat added to the sample of gold. The heat required or added to raise the temperature is given by :
[tex]Q=mc\Delta T[/tex]
c is the specific heat of gold, [tex]c=0.129\ J/g^{\circ} C[/tex]
Putting all the values,
[tex]Q=8.21\times 0.129\times 6.2\\\\=6.56\ J[/tex]
So, 6.56 J of heat is added to the sample of gold.
