A water molecule starts in hot bath water and ends up on the surface of the bathroom mirror. Which of the following most likely happened during the transition? (2 points) Some of the water molecules became vapor, then condensed back into droplets on the mirror. The water from the bath evaporated and turned solid on the mirror. The water in the bath solidified, then melted and evaporated before ending up on the mirror. Some of the water molecules condensed on the side of the tub, then melted back into vapor to travel to the mirror.

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.
