Flashcards: Heat Transfer and Thermal Equilibrium

\(\displaystyle 1.4 kJ\) of energy is applied to an aluminum rod of unknown mass. Its temperature goes from \(\displaystyle 20^{\circ}C\) to \(\displaystyle 45^{\circ}C\). What is the mass of the rod?

\(\displaystyle c_{aluminum}= 0.900 \frac{J}{g^{\circ}C}\)

\(\displaystyle 34.57 g\)

\(\displaystyle 77.78 g\)

\(\displaystyle 62.22 g\)

\(\displaystyle 50.40 g\)

There is not enough information to determine the rod's mass

AP Physics 2 is a year long, advanced placement course that introduces essential physics. The course covers a wide range of topics, such as thermodynamics, fluid statics and dynamics, electrostatics, DC and RC circuits, magnetism and electromagnetic induction, geometric and physical optics, and quantum, atomic, and nuclear physics. The College Board refers to these concepts as the seven “big ideas,” an apt nickname given that the topics include quantum and nuclear physics. This curriculum framework presents many ideas that were not previously taught in the first portion of this course, AP Physics 1, and some serious study time may be necessary if you want to ace the exams in this course. For help mastering these “big ideas,” look no further than Varsity Tutors’ free Learning Tools to find an abundance of AP Physics 2 study help. There you will find a comprehensive selection of Learning Tools that cover the broad spectrum of the curriculum, including thousands of AP Physics 2 flashcards. Whether you need top Physics tutors in ConnecticutPhysics tutors in Dayton, or top Physics tutors in Las Vegas, working with a pro may take your studies to the next level.

The seven principles that comprise the course are all represented by a multitude of flashcards and cover the learning objectives and essential knowledge that the course requires, as mandated by the College Board. Various topics are sorted into large categories and broken down into smaller sub-groups so you can concentrate on the most relevant material or broaden your focus to encompass the bigger subjects. You can even build your own deck of flashcards to further customize the Learning Tools for a more personalized learning experience. The advantage of using flashcards as a study aid is the immediate reinforcement of correct information. Learning Tools Flashcards provide direct feedback and allow you to address any weak areas that may need more attention. Repeated practice with flashcards helps embed important details in your memory, enabling an easier understanding of the much larger concepts discussed in AP Physics 2. Varsity Tutors offers resources like free AP Physics 2 Practice Tests to help with your self-paced study, or you may want to consider an AP Physics 2 tutor.
