Typically, scuba tanks are immersed in water to cool them as they are filled with compressed air. If a tank is initially charged to 1.90E+03 psi at 39.0 C and subsequently allowed to cool to 25.0 C, what is the final pressure in the tank?
Two new materials have been discovered. One is shinyand has a metallic look, while the other is dull andhas a non-metallic look. Although you think that oneis a conductor and the other an insulator, you wantto be certain. Describe a test you could do to test theconductivity of these two materials.
A close analogy exists between the flow of energy by heat because of a temperature difference (see Section 19.6) and the flow of electric charge because of a potential difference. In a metal, energy dQ and electrical charge dq are both transported by free electrons. Consequently, a good electri- cal conductor is usually a good thermal conductor as well. Consider a thin conducting slab of thickness dx, area A, and electrical conductivity ơ, with a potential difference dV between opposite faces. (a) Show that the current I = dq/dt is given by the equation on the left: Charge conduction Thermal conduction dq = oA dt dT kA dt dQ AP dx dx In the analogous thermal conduction equation on the right (Eq. 19.17), the rate dQ/dt of energy flow by heat (in SI units of joules per second) is due to a temperature gradient dT/dx in a material of thermal conductivity k.
