Document Summary
Latent heat: p p top + gh va. Average molecular energy per degree of freedom: kb t. Show your work, don"t just write the results. The container is slowly filled with mercury (density m> w) until the container sinks: calculate the level of mercury in the container just before it sinks. If instead of mercury the container is completely filled with oil (density o< w), the container does not sink: calculate in this case the length h2 of the container that is below the water level. A mixture of water and ice is in thermal equilibrium at temperature tw in a thermally insulated container at atmospheric pressure. A rod of aluminum (thermal conductivity k) has one end immersed in the mixture and the other one in contact with a system that is kept at constant temperature th>tw (see figure). The rod has radius r for a length x from the system and then its radius is reduced to r/2.
