Lower Sec Science · Secondary 1 · Hard · Arrangement of particles
A student states that in a solid, the particles have low energy and are very close together. In a gas, the particles have high energy and are far apart. Which row correctly shows how the energy of the particles and the space between them change when a solid melts to become a liquid?
- energy decreases, space between particles decreases
- energy decreases, space between particles increases
- energy increases, space between particles increases
- energy increases, space between particles stays the same
