An isothermal change lmk9q 0 ciloviwus2t+h,5u *4 ol 1a8g6 opzp3 et*ej7mh4jb n7.ni+ww f a gas at $63^{\circ}C$ occurs by transferring $3360\,J$ of heat energy to the surrounding medium.
A. $-53.3\,J\,K^{-1}$
B. $-10\,J\,K^{-1}$
C. $10\,J\,K^{-1}$
D. $53\,J\,K^{-1}$
参考答案: B
本题详细解析:
Explanation: The entropy is given by$S=\frac{ΔQ}{T}$ Since the heat energy is leaving the gas Then$S=-\frac{3360}{63\times273}$=$-\frac{3360}{336}$=$-10\,J\,K^{-1}$
