A) \[{{Q}_{4}}>{{Q}_{3}}>{{Q}_{2}}>{{Q}_{1}}\]
B) \[{{Q}_{4}}>{{Q}_{3}}>{{Q}_{1}}>{{Q}_{2}}\]
C) \[{{Q}_{4}}>{{Q}_{2}}>{{Q}_{3}}>{{Q}_{1}}\]
D) \[{{Q}_{4}}>{{Q}_{2}}>{{Q}_{1}}>{{Q}_{3}}\]
Correct Answer: A
Solution :
[a] \[{{Q}_{4}}=m{{L}_{w}}=540\,cal\] \[{{Q}_{3}}=m{{s}_{w}}(100-0)=100\,cal\] \[{{Q}_{2}}=m{{L}_{ice}}=80\,cal\] \[{{Q}_{1}}=m{{s}_{ice}}=(20-0)=20\,cal\] \[{{Q}_{4}}>{{Q}_{3}}>{{Q}_{2}}>{{Q}_{1}}\]You need to login to perform this action.
