Help to calculate the answer of the following problem
Problem- Small object begins a free-fall from a height-
Part A- Calculate the minimum amount of energy, in joules, required to completely melt 102 g of silver initially at 42.0°C. The melting point of silver is at 962°C. Its specific heat capacity is 236 J/kg·K and its latent heat of fusion is 105kJ/kg.
Part B- What mass of steam at 100°C must be mixed with 136 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 50.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333kJ/kg, and the latent heat of vaporization is 2256 kJ/kg.
You need help to calculate the accurate answer of the above problem.
