1. A light bulb operates at a temperature of 4,300 K and has an emissivity of 0.600 and a surface area of
5.50 mm². How long would the light bulb have to shine on a 2.00 g piece of ice that is at -30.0°C in
order to turn the ice into steam at 120°C? Assume all the energy radiated by the light bulb is absorbed
by the ice while it becomes liquid and eventually steam. Give an answer in seconds.
