**Thermodynamics and Energy Changes** In each case below, calculate the missing quantity in the table: | | q | w | ΔE | |----|--------------------------------------|-------------------------------------|---------------------------------| | a. | 100 J of heat flows in | System does 40 J of work | | | b. | 200 J of heat is added | No work is done | | | c. | 500 J of heat is added | System does 350 J of work | | | d. | 70 J of heat is removed from a gas | 70 J of work is done to compress the gas | | | e. | | Expanding gas does 500 J of work | Internal energy increases by 340 J | | f. | You lose 9.0 x 10^5 J of heat playing basketball | | Your internal energy decreases by 1.20 x 10^6 J | | g. | No heat is added | 40 J of work done to compress a gas | | **Explanation of Diagrams:** The image below the table contains three diagrams illustrating the concepts of heat (q) and work (w) in thermodynamic processes: 1. **Diagram (a):** - Represents a system where \( q < 0 \), meaning heat is leaving the system. - Arrows point outward to indicate heat flowing out. 2. **Diagram (b):** - Illustrates a scenario with \( w < 0 \), indicating that work is done on the system. - The piston moves inward, reflecting work being applied to compress the system. 3. **Diagram (c):** - Shows a situation where \( q > 0 \) and \( w > 0 \), meaning heat is entering the system and work is done by the system. - The piston moves outward, reflecting expansion as the system performs work and absorbs heat. These diagrams help visualize the relationships between heat transfer, work done, and changes in internal energy in thermodynamic processes.
