The answer would be option e
D. The trend for first ionization energy
Answer:
The correct option is (c).
Explanation:
Given that,
Mass of iron, m = 3 kg = 3000 g
The temperature of ice increases from 20°
C to 25°C.
The specific heat of iron is 0.45 J/g°C
We need to find the energy required to raise the temperature. The formula is given by :
So, 6750 J of energy is required to raise the temperature or iron.
