Lets consider the temperature difference to be a function of time then T=kt k is a arbitary constant
rn
Then heat current at any time t = dQ/dt= KA T/l => dQ/dt = KA kt/l
rn
Q= ∫KA kt/l.dt= KA kt2/2l
rn
Since T=kt then t= T/k
rn
Q= KAT2/2kl
rn
So kthe rate at which temperature is varied with time shold be specified for solution
