A force F = 2i 3j + k acts at the point (1, 5, 2). Find the torque due to F (a) about the origin; (b) about the y axis; (c) about the line x/2 = y/1 = z/(2)

Consider the phase change taking place in the picture. you could use all but one statement to describe what is happening here. that is: a) temperature is increasing. b) kinetic energy is increasing. c) the space between the particles remains the same. d) the attractive force between the particles is decreasing.
