Thermodynamics [FINAL EXAM]-Questions and Answers Graded A+ Kinetic Energy and Potential Energy are extensive properties of a system. - ANSWER-True Work is not a property - ANSWER-True It is correct to say that a system contains heat. - ANSWER-False. Heat is a mode of energy transfer and can only be recognized at a system boundary. It is not a property of a system. The change in total energy of a closed system other than changes in kinetic and gravitational potential energy are account...
