a. Rank in order, from highest to lowest, the temperatures $T_1=0K,T_2=0{}^{\circ }\mathrm{C}$, and $T_3=$ $0^{\circ }\mathrm{F}$ b. "Room temperature" is often considered to be $68^{\circ }\mathrm{F}$. What is room temperature in ${}^{\circ }\mathrm{C}$ and in $\mathrm{K}$ ? Q3. First Law of Thermodynamics: For each of the following processes: a. Is the value of the work $\mathrm{W}$, the heat $\mathrm{Q}$, and the change in thermal energy $\Delta \mathrm{Eth}$, positive $(+)$, negative $(-)$ or zero $(0)$ ? b. Does the temperature increase $(+)$, decrease $(-)$, or not change $(0)$ ? Make sure your answers are consistent with the first law of thermodynamics.
