Answers to Socrative Quiz Heat/Temperature Topic 4,5,6 1. D – Melting 2. A – Boiling 3. C – Ionization 4. B – Evaporative Cooling 5. B - False – During a phase change the average energy remains the same 6. B - False – you would see a graph looking like steps because the temperature does not change during a phase change 7. D – Latent Heat 8. E – Sublimation 9. A – True – A substance always gains energy when changing from liquid to gas (evaporation) and always loses energy when changing from liquid to solid (freezing) 10. D – Volcanoes and Lava 11. B – Reduction 12. A – Transfer of energy without movement of particles 13. D – Transfer of energy by collisions of particles 14. E – Transfer of energy by movement of particles 15. A – True – Gamma rays have the smallest wavelength and therefore the highest energy 16. B – False – Radiowaves have the lowest energy, but the longest wavelength 17. A – Radiowaves, microwaves, infrared, Visible light, UV, Gamma Rays 18. C – Energy Source, Energy Transfer, Control System, Waste as heat 19. B – False – Insulators slow down the rate of conduction (Think insulation in a house keeps the house warm by slowing down the heat loss 20. B – False – The circular movement of fluids while heating is called a convection current. (Think convection oven)
