• 2. The more heat (thermal energy) that is stored in a substance , the higher the what? (11)
• 3. Name one way that thermal energy can be transferred. Objects that are touching can transfer thermal energy, from the hotter object to the cooler one. (10)
• 4. When hot air is less dense and therefore rises. Cold air is more dense and therefore sinks. This creates a what current? (10)
• 6. What quantity is stored in many objects and situations. Anything storing this can do work? (6)
• 7. Name a way that thermal energy can be transferred. All objects give out infra red ........?....... Hotter objects give out (emit) infra red ........?........ that is absorbed by cooler objects. (9)
• 8. What is the energy stored in substances thanks to the energy of their particles. Also called thermal energy? (4)
• 9. What is done when energy changes from one store to another? (4)
• 10. what is the measure of the average amount of kinetic energy of tall the particles in a substance? (11)
