Imagine a system, that can keep the room temperature within a narrow range between 20^@C to 25^@C . The system includes a heat engine operating with variable power P = 3KT, where K is a constant coefficient, depending upon the thermal insulation of the room, the area of the walls and the thickness of the walls. T is temperature of the room in temperature drops lower than 20^@C , the engine turns on, when the temperature increase over 25^@ C, the engine turns off, room looses energy at a rate of K(T - T_0), T_0 is the outdoor temperature. The heat capacity of the room is C. Given (T_0=10^@C, ln(3/2) =0.4 , ln(6/5)=0.18 , C/K =750 SI-unit) Suppose at t = 0, the engine turns off, after how much time interval, again, the engine will turn on

Assertion (A): wedge_(m(H^(o+))) and wedge_(m(overset(c)(O)H)) ions are very much higher than those of other ions. Reason (R): It is due to proton jump from one water molecule to another resulting in a more rapid transfer of positive charge form one region to another. (a)If both (A) and (R) are correct, and (R) is the correct explanation of (A) . (b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A) . (c)If (A) is correct, but (R) is incorrect. (d)If (A) is incorrect, (R) is correct.
