Calculate the voltage of the cell , by considering the following reactions: By the

An Introduction to Thermal Physics 1
Problem 35P According to the Sackur-Tetrode equation, the entropy of a monatomic ideal gas can become negative when its temperature (and hence its energy) is sufficiently low. Of course this is absurd, so the Sackur-Tetrode equation must be invalid at very low temperatures. Suppose you start with a s

Problem 5PE Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed

Consider a mixture of the two solids, BaCl2 2H2O (FM 244.26) and KCl (FM 74.551), in an unknown ratio. (The notation BaCl2  2H2O means that a crystal is formed with two water molecules for each BaCl2.) When the unknown is heated to 160C for 1 h, the water of crystallization is driven off: A sample

Segway for Information Workers The Segway Human Transporter is a self-balancing personal transportation vehicle that is clean (battery powered) and small (its footprint is 19 by 25 inches) so it can be used on sidewalks and inside buildings. Suppose the segway is introduced into a CBD, doubling the s
