Answer:
375 and 450
Explanation:
The computation of the initial and the final temperature is shown below:
In condition 1:
The efficiency of a Carnot cycle is
So, the equation is
For condition 2:
Now if the temperature is reduced by 75 degrees So, the efficiency is
Therefore the next equation is
Now solve both the equations
solve equations (1) and (2)
T_2 + 450 = 75
T_2 = 375
Now put the T_2 value in any of the above equation
i.e
T_1 = T_2 + 75
T_1 = 375 + 75
= 450
