What happens to a material when it changes from a solid state to a liquid state?
What happens to a material when it changes from a solid state to a liquid state?
- Its particles lose energy and move more slowly
- Its particles become more tightly packed
- Its particles change in size and shape
- Its particles gain energy and move more freely (correct)
What effect does heat have on the particles of a material in a solid state?
What effect does heat have on the particles of a material in a solid state?
- It has no effect on the particles
- It increases the kinetic energy of the particles (correct)
- It decreases the kinetic energy of the particles
- It changes the composition of the particles
