Question

What is the total heat gained by an 8 gram piece of iron that increases in temperature by 6 C

Answer 1

Answer:21.6 Joules

Step-by-step explanation:

`Q= m* c* \Delta T`

Q= heat gained

m= mass of the substance = 8g

c = heat capacity of iron= 0.45 J/g ° C

`\Delta T={\text{Change in temperature}}=6^oC`

`Q=8g* 0.45J/g^oC*6^oC`

Q= 21.6 Joules

Thus heat gained by 8 g of iron is = 21.6 Joules
