A) \[{{T}_{1}}={{T}_{2}}\]
B) \[{{T}_{1}}=2{{T}_{2}}\]
C) \[{{T}_{1}}=4{{T}_{2}}\]
D) \[{{T}_{2}}=9{{T}_{1}}\]
Correct Answer: A
Solution :
Suppose heat evolved in 1st case is\[{{Q}_{1}}\]and that in the 2nd case it is\[{{Q}_{2}}\]. Then\[{{Q}_{2}}=\frac{1}{2}{{Q}_{1}}\] But \[{{Q}_{1}}=1000\,{{T}_{1}}\] and \[{{Q}_{2}}=500\,{{T}_{2}}\] \[\therefore \]\[500\,{{T}_{2}}=\frac{1}{2}\times 1000\,{{T}_{1}}\] i.e., \[{{T}_{2}}={{T}_{1}}\]You need to login to perform this action.
