Solving problems involving the change in internal energy of a system using AU = Q-W If a system has 30 J of heat added to it, and it does 20 J of work, what is the change in its internal energy?
Answer (2)
Binanog and Wayang Kulit share profound cultural roots and serve similar functions in storytelling, artistic expression, community engagement, and education within their respective societies.Similarities in Cultural Significance:Both are vital expressions of their cultures, preserving traditions and values.Each serves as a narrative medium, conveying cultural tales and morals through performance.Binanog features intricate dance, while Wayang Kulit uses shadow puppetry, both showcasing artistic expression.Both forms are enhanced by traditional music—Binanog with dance music and Wayang Kulit with gamelan.They foster community involvement during festivals, strengthening social bonds.Both educate audiences about cultural heritage and instill values through their performances.
- ΔU = change in internal energy - Q = heat added to the system (positive if added, negative if removed) - W = work done by the system (positive if work is done by the system, negative if work is done on the system) We have: Q = +30 J (heat added)W = +20 J (work done by the system) Therefore: ΔU = 30 J - 20 J = 10 J The change in internal energy of the system is10J
