Specific latent heat of fusion of ice is 334 J/g. How much energy is needed to melt 100 g of ice at 0oC.
Correct answer: B. 33.4 kJ
- A. 33.4 J
- B. 33.4 kJ
- C. 3.34 J
- D. 3.34 kJ
Explanation
Correct Option: BTo calculate the energy needed to melt 100 g of ice at 0°C, we need to use the specific latent heat of fusion of ice, which is given as 334 J/g.Energy = Specific latent heat of fusion × MassEnergy = 334 J/g × 100 g = 33400 JSince the answer options are given in different units, we need to convert the energy to the appropriate unit.B) 33483 is the closest option in the list and represents the energy in joules (J)

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
