.Question 10Consider a dropping a ball from a height of 5 m into a pool of warm water. Which of the following is true?1 pointThere is a change in internal energy in the process. Energy is not conserved. The potential energy can be ignored. There is significant work transfer. 11.Question 11In this course, we commonly assume

A girl drops a basketball off of a dam and it falls freely. Which of the following is true? The ball's kinetic energy increases by equal amounts in equal distances. The ball's kinetic energy increases by equal amounts in equal time intervals.

10 A ball is dropped on to a hard surface and bounces. It does not bounce all the way back to whereit started, so it has less gravitational potential energy than when it started.hard surfaceball droppedfrom hereball bouncesto hereWhat happens to the ‘lost’ energy?A It is converted into chemical and strain energy.B It is converted into internal (heat) energy and sound.C It is destroyed as the ball rises upwards after hitting the ground.D It is destroyed when the ball hits the ground.11 What does a barometer measure?A atmospheric densityB atmospheric pressureC liquid densityD liquid pressure12 In which position would a boy exert the most pressure on the ground?A lying on his backB sitting downC standing on one footD standing on two feet6© UCLES 2012 0625/12/M/J/1213 On a warm day, a swimmer climbs out of a swimming pool into the open air and water evaporatesfrom his skin.As the water evaporates, which molecules escape into the air first and what happens to theaverage speed of the remaining water molecules?first moleculesto escapeaverage speed of theremaining moleculesA least energetic decreasesB least energetic increasesC most energetic decreasesD most energetic increases14 Some air is trapped inside a metal can with a tightly fitting lid.airheattightly fitting lidmetal canWhen the can is heated strongly behind a safety screen, the lid is blown off by the increasedpressure inside the can.What causes the increase in pressure of the air inside the can?A The air molecules expand and take up more room.B The air molecules move more quickly.C The number of molecules inside the can increases.D The volume occupied by the molecules decreases.15 A solid object has a very large thermal capacity.What does this mean?A A large amount of energy is needed to make the object become hot.B A large amount of energy is needed to make the object melt.C A small amount of energy is needed to make the object become hot.D A small amount of energy is needed to make the object melt
