41. a 10.0-m3 tank contains steam at 275°c and 15.0 bar. the tank and its contents are cooled until the pressure drops to 1.8 bar. some of the steam condenses in the process. (a) how much heat was transferred from the tank? (b) what is the final temperature of the tank contents? (c) how much steam condensed (kg)?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared
