Problem 38E

A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in Figure 5.4. When $$0.49 \ kJ$$ of heat is added to the gas, it expands and does $$214 \ J$$ of work on the surroundings. What are the values of $$\Delta H$$ and $$\Delta E$$ for this process?

1/11/17 PHYS 202 The syllabus is online Chapter 11 Preview: The basic Energy Model  This chapter is about thermal energy, chemical energy, and energy transfers in the form of heat  Work and heat are energy transfers that change the system’s total energy. If the system is isolated, the total energy is conserved o If energy goes into the system from the environment, the system’s energy increases, opposite the system loses energy  If Environment pushes an object, kinetic energy is exerted thus moving the object. Then it stops based on friction, increasing the thermal energy, then it leaves and cools. Clicker Question: Christina throws a javelin into the air. As she propels it forward from the rest, she does 270J of work on it. At its highest point, its gravitational potential energy has increased by 70J. What is the javelin’s kinetic energy at this point 200J (she does work on the system, you change kinetic energy, then it’s flying in the air, subtracting 70 J). Section 11.1: Transforming Energy Transforming Energy The work-energy equation includes work, an energy transfer. We now include electric and radiant energy in our definition of work: E e e = K + U + th + chem + ... = W  Work is positive when energy is transferred into the system and negative when energy is transferred out of the system o Ex: Exerting energy on a little machine  When other forms of energy are transformed into ther
