A) \[\frac{{{t}_{1}}}{{{t}_{1}}-{{t}_{2}}}\]
B) \[\frac{{{t}_{1}}+273}{{{r}_{1}}-{{t}_{1}}}\]
C) \[\frac{{{t}_{2}}+273}{{{t}_{1}}-{{t}_{2}}}\]
D) \[\frac{{{t}_{1}}+{{t}_{2}}}{{{t}_{1}}+273}\]
Correct Answer: B
Solution :
\[K=\frac{{{Q}_{2}}}{W}=\frac{1}{\frac{{{t}_{1}}}{{{t}_{2}}}-1}\] \[{{Q}_{2}}=\frac{{{t}_{2}}W}{{{t}_{1}}-{{t}_{2}}}\] \[{{Q}_{1}}={{Q}_{2}}+W=\frac{{{t}_{2}}W}{{{t}_{1}}-{{t}_{2}}}+W\] \[\frac{{{t}_{1}}W}{{{t}_{1}}-{{t}_{2}}}=\frac{{{t}_{1}}+273}{{{t}_{1}}-{{t}_{2}}}\]You need to login to perform this action.
