Imagine that you place a piece of copper with an initial temperature of 20°c in contact with some liquid water with an initial temperature of 100°c. assume that the physical system consisting of the copper and the water is thermally isolated from everything else; i. e., they can only exchange energy with each other.
a) sketch two three-phase diagrams, one for each substance, and mark the initial state for each one. explain in a sentence or two how you can tell if either substance will undergo a phase change during the process of coming to thermal equilibrium. you do not need to do any calculations.

its c its is a mixture of gases

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
