A dark red clay brick in space is continuously exposed to sunlight such that it absorbs 10 Watts of electromagnetic power. But under these conditions the brick's temperature is observed to be constant. a) Describe the energy flows into and out of the brick - what mechanisms are involved, and what are the relative sizes of those energy flows? b) The brick is instantly, painted black. (Don't worry about how.) Do the energy flows and temperature change? Explain.
