In this paper, we study the quenching behavior of solution of a nonlinear parabolic equation
with a singular boundary condition. We prove finite-time quenching for the solution. Further,
we show that quenching occurs on the boundary under certain conditions. Furthermore, we
show that the time derivative blows up at quenching point. Also, we get a lower solution and
an upper bound for quenching time. Finally, we get a quenching rate and lower bounds for
quenching time.
