Can there be a time temperature graph as follows? Justify you're answer:

The torque acting on a body about a given point is given by $ \tau = \overrightarrow{A} \times\overrightarrow{L} $ where $ \overrightarrow {A} $ is a constant vector and $ \overrightarrow {L} $ is the angular momentum of the body about this point. It follows that
