Ryan is testing two types of light bulbs to see how efficiently they use energy. one is a standard incandescent bulb, and one is a compact fluorescent bulb. ryan turns both bulbs on and finds that, after an hour, the incandescent bulb is too hot to touch, while the compact fluorescent bulb is warm, but not hot. incandescent bulb compact fluorescent bulb if the purpose of both bulbs is to transform electrical energy into light energy, what can ryan infer from his findings?

Asolid steel sphere (k=63.9 w m-1 k-1 , ? =7832 kg m-3 , c=0.523 kj kg-1 k-1 ), 100 mm in diameter is initially at a uniform temperature of 500o c and is suddenly quenched in a large oil bath for which t? = 100o c and h = 3200 w m-2 k-1. estimate the time required for the sphere to cool to 200o c and to 110o c
