Question

How does the movement of particles in a stick of butter differ from the movement of particles in a dish of melted butter?

Answer 1

particles in the butter stick  are solids which move about their mean or fixed positions unlike liquid particles in the melted butter that move more freely than solids.

Answer 2

if I'm correct, the particles in the stick of butter do not move because it is a solid. the particles in the dish of melted butter will move because it is a liquid.
