A) \[{{50}^{o}}C\]
B) More than \[{{50}^{o}}C\]
C) Less than\[{{50}^{o}}C\]but greater than \[{{0}^{o}}C\]
D) \[{{0}^{o}}C\]
Correct Answer: B
Solution :
Loss of heat by hot body = Gain of heat by cold body \[{{T}_{{{c}_{1}}}}\Delta {{\theta }_{1}}={{T}_{{{c}_{2}}}}\Delta {{\theta }_{2}}\] \[{{T}_{{{c}_{1}}}}>{{T}_{{{c}_{2}}}}\Rightarrow \Delta {{\theta }_{1}}<\Delta {{\theta }_{2}}\]
