*7. 00 A copper-constantan thermocouple generates a voltage of 4.75 x 10-
volts when the temperature of the hot junction is 110.0 °C and the refer-
ence junction is kept at a temperature of 0.0 °C. If the voltage is propor-
tional to the difference in temperature between the junctions, what is the
temperature of the hot junction when the voltage is 1.90 × 10-³ volts?

b) Use the preceding result to prove that for an ideal gas, Cy is a function
of T only.
Experimentally it appears that many polyatomic molecules’ vibrational degrees of freedom can contribute to some extent to their energy at room temperature. Would you expect that fact to increase or decrease their heatcapacity from the value R? Explain.

- When a metal is heated, its atoms vibrate more about their position in the lattice (a network of crossed bars). This causes them to take up more space, so the solid metal expands from its original shape.

- Why is metal a better conductor of heat than non-metals? In metals, apart from transferring heat energy by the relatively slow process of molecular collision, another faster process of free electron diffusion takes place. Metals contain free electrons that are mobile. When heated, these free electrons gains KE and will diffuse to the cooler end at high speeds. In the process, they will collide with atoms at the cooler end and transfer kinetic energy to them.arrow_forward3.

Several of the ongoing projects use liquid helium, which is contained in a thermally insulated vessel that can hold up to a maximum of Vmax = 240 L of the liquid at Tc = 4.20 K. Because some of the liquid helium has already been used, someone asks you to check to see if there is enough for the next day, on which four different experimental groups will need liquid helium. You are not sure how to measure the amount of liquid remaining, so you insert an aluminum rod of length L = 2.00 m and with a cross-sectional area A = 2.50 cm2 into the vessel. By seeing how much of the lower end of the rod is frosted when you pull it out, you can estimate the depth of the liquid helium. After inserting the rod, however, one of the experimenters calls you over to perform a task and you forget about the rod, leaving it in the liquid helium until the next morning. How much liquid helium is available for the next day’s experiments?…arrow_forward
