A expansion of a liquid C resistance of a metal B D mass of a liquid volume of a liquid A B c D Smoke particles in a transparent box are observed using a microscope. A small point of light is seen to move around as shown. What does this experiment demonstrate about air molecules? They are in continuous random motion. They can be seen through a microscope. They move more quickly when they are heated. They move because of collisions with smoke particles. PartnednLeaming 201

BP -?O? 7 15 17 16 A thin tube contains a thread of mercury which traps air at the end of the tube. The other end of the tube is open to the atmosphere. trapped ak intbe threed of me[cury trappBd 8it in 1ub3 When the tube is turned upside down, the volume of the trapped air increases. Which statement explains this? The pressure of the trapped air is reduced. The atmosphere pushes less when it acts upwards on the mercury. The air gets hotter when the tube is turned upside down. The trapped air molecules hit the mercury harder when travelling downwards. ln cold countries, animals usually grow thicker layers of fur in winter to keep them warm. What is the best explanation of why this extra fur keeps them warm? It is a good conductor of heat. It is a poor conductor of heat. It traps more air, which is a good conductor of heat It traps more air, which is a poor conductor of heat. conduction and convection only convection only conduction only conduction, convection and radiation A B c D A B c D A B c D ln a vacuum flask, which methods of heat transfer are prevented by the vacuum?
