A solid disk of radius R and mass M is spinning in a frictionless environment with angular velocity w1 at temperature T1. The temperature of the disk is then changed to T2. Express the angular velocity w2, rotational kinetic energy E2, and angular momentum L2 in terms of their values at the temperature T1 and the linear expansion coefficient a of the disk.
