A toy robot when turned on lights project a sound and started to walk .what are the energy transformations that has undergone by the toy .trace energy and its transformation.
A toy robot may have a batter as the source of energy. Battery has a stored energy in it to be specific, potential chemical energy which can be converted to some other forms of energy.
Chemical Energy ⇒ electrical energy ⇒ light energy ⇒ thermal energy
electrical energy ⇒ sound energy (project a sound)
electrical energy ⇒ mechanical energy (walk)
Hope it helps...=)
It was the Kepler's second law of planetary motion, or The Law of Equal Areas in Equal Time. It was the line between a planet and sun sweeps out equal areas in the plane of planet's orbit over equal times. It was also describing the speed of the planet traveling in a elliptical orbit around the sun.

Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature. (Wiki)
So by that definition you can expand solids, liquids, and gas by changing its temp
