The most probable answer is: (a) <span>The black pot emits heat at a faster rate than the silver pot. It means the black pot conducts heat at a higher rate than the silver pot, that's why it cooled off faster. It also means that the silver pot retains heat better and is more of an insulator.</span>
The speed of the mouse is 11 ft/s
Answer:
C. T>617 K
Explanation:
We are given that
We have to find the temperature at which the reaction is spontaneous.
When
Therefore, the reaction is spontaneous at certain range of temperature.
Option A is not true.
When is negative, then the reaction is spontaneous.
When T<50
Suppose T=49 K
Therefore, .Hence, the reaction is not spontaneous.
Option B is wrong.
C.T>617K
Suppose T=618 K
Therefore, .Hence, the reaction is spontaneous.
So, option C is true.
D.T<617 K
Suppose T=616 K
Therefore, .Hence, the reaction is not spontaneous.
So, option D is not true.
