Particle model of matter
Lower Sec Science · Secondary 1 · Medium · Particle model of matter
A metal block is heated strongly at one end. After some time, the other end also becomes hot. Which statement best explains this using the particle model?
- Particles at the hot end vibrate faster and pass energy to neighbours by collisions
- Hot particles move from the hot end to the cold end, carrying heat with them
- Electrons leave the metal and heat the air, which then heats the far end
- Particles at the cold end start vibrating faster without receiving any energy
