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

Explanation:

$Q= m\times c\times \Delta T$

Q= heat gained

m= mass of the substance = 8g

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

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

$Q=8g\times 0.45J/g^oC\times6^oC$

Q= 21.6 Joules

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