Question

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

Answer 1

Q = 6.56 J

Step-by-step 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 :

`Q=mc\Delta T`

c is the specific heat of gold,
`c=0.129\ J/g^(\circ) C`

Putting all the values,

`Q=8.21* 0.129* 6.2\\\\=6.56\ J`

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