Answer 2

Answer:

2137.5J  is the heat required to increase the temperature by 10°C of the iron bob of mass 10 gm.

Explanation:

Difference in temperature ΔT =(500- 25) =475°C

Specific heat = 0.45J/g°C [given]

mass = 10g [given]

Q= mass × specific heat × ΔT

                                                                   [where Q= energy required

                                                                       ΔT= difference in temperature]

Q= 10g × 0.45J/g°C × 475°C

  = 2137.5 J
