Estimate the temperature of agiven lightbulb

Reference no: EM13646615

The temperature of the glass surface of a 30 W lightbulb is 75°C when the room temperature is 18°C. Estimate the temperature of a 150 W lightbulb with a glass bulb thesame size. Consider only radiation, and assume that 90% of theenergy is emitted as heat.
