The forces of attraction between the particles of a matter sample are strong and draw particles together, keeping them in their place. This is an example
of the solid state of matter
When a liquid boils, its particles get ____.
further apart
When thermal energy is added to a solid, its temperature increases, as does the speed of its particles and the distance between them. What happens to a gas when thermal energy is added?
Multiple choice question.
A) Its temperature decreases, as does the speed of its particles and the distance between them.
B) Its temperature increases, as does the speed of its particles and the distance between them.
C) Its temperature remains the same because all the energy causes the particles to spread farther apart.
D) Its temperature stays the same, but the speed of its particles and the distance between them increases.
B)
Its temperature increases, as does the speed of its particles and the distance between them.
