How much heat must be added to 8.21 g sample of gold to increase its temperature by 6.2°C?

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 :

c is the specific heat of gold,

Putting all the values,

So, 6.56 J of heat is added to the sample of gold.
