Help your students build real, exam ready understanding of first law of thermodynamics through ninety questions that move from basic recognition to genuine problem solving.
Students will answer questions such as "A gas absorbs 600 J of heat while doing 400 J of work. What is the change in internal energy?", "A system releases 250 J of heat and does 100 J of work. What is the change in internal energy?", and "If a system absorbs 400 J of heat and does 300 J of work, what is the change in internal energy?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a complete AP Physics unit. The unit also covers Entropy and the Second Law, Heat Engines and Efficiency, Heat Transfer Mechanisms, Ideal Gas Law Applications, Kinetic Theory Basics, and Specific Heat and Calorimetry, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 AP Physics classes, and for review at any point in the school year.
