D. 5.0 g of water at 25°C is dropped onto a large block of ice at 0 °C. The water cools to 0 °C and
some of the ice melts. Assume that all the energy lost by the water is gained by the ice. What is
the mass of ice that melts? The specific heat capacity of water is 4.2J/(g°C). The specific latent
heat of fusion of ice is 340J/g.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
