$.$ Temperature: a$.$ Rank in order, from highest to lowest, the temperatures T$\_\{$I$\}=0$K T$\_\{2\}=0$ deg $*$ C and T$\_\{3\}=0$ deg $*$ F b$.$ "Room temperature" is often considered to be $68$ deg $*$ F What is room temperature in $^$ C and in K$?$ c$.$ What is the average kinetic energy of atoms at absolute zero? d$.$ Is it possible to have a temperature less than absolute zero? Explain.
