A solid body X of heat capacity C is kept in an atmosphere whose temperature is T_A=300K . At time t=0 the temperature of X is T_0=400K . It cools according to Newton's law of cooling. At time t_1 , its temperature is found to be 350K. At this time (t_1) , the body X is connected to a large box Y at atmospheric temperature is T_4 , through a conducting rod of length L, cross-sectional area A and thermal conductivity K. The heat capacity Y is so large that any variation in its temperature may be neglected. The cross-sectional area A of hte connecting rod is small compared to the surface area of X. Find the temperature of X at time t=3t_1.
