1) Which of these is a unit of heat? a) J b) oC c) K d) N e) m3 f) kiloJoules 2) Which of these is a unit of temperature? a) J b) oC c) K d) N e) m3 f) kiloJoules 3) Block A has a mass of 10g and a temp of 25oC. Block B has a mass of 80g and a temp of 25oC. Compare their temperature. a) A and B have the same average kinetic energy of their particles b) A and B have the same total thermal kinetic energy c) If A and B touch, their temperature will stay the same d) If A and B touch, A's temp will get hotter e) If A and B touch, B's temp will get hotter f) A and B have the same temperature 4) Block A has a mass of 10g and a temp of 25oC. Block B has a mass of 80g and a temp of 25oC. Compare their heat. a) A and B have the same average kinetic energy of their particles b) A and B have the same total thermal kinetic energy c) Heat will flow from A to B d) A has more heat than B e) B has more heat than A f) Heat will not flow between the two because temp is the same 5) In which direction will thermal energy be transferred? a) A --> B only b) A --> C only c) A --> B and A --> C d) A --> B and A --> C and B --> C e) C --> B and C--> A f) B --> A and C--> B 6) If object X has a higher temperature than object Y, then X must always have more heat than Y. Is this statement true or false and WHY? a) True only if the substances are the same and have the same mass b) False, a small mass object can have a higher temperature than an object with a larger mass, yet the object with larger mass may have more heat. c) False, a large mass object can have a higher temperature than an object with a smaller mass, yet the object with smaller mass may have more heat.
