Energy Magnitudes for Thermal Processes


“How much energy is necessary to warm up some air or water (you choose the amount)?”


This SWBQ is designed to be very general to force students to consider what important factors could change the answer, such as the temperature, volume, or pressure of the sample, and whether any of those parameters are being held constant. Whenever performing a calculation in any physics problem, one should have a general idea of the magnitude of the answer. By the end of this SWBQ, students should have an idea of the energy necessary to heat water or air, particularly in terms of the specific heat.
