Examples of phase energy
Webthe orbit in phase space corresponding to a certain energy is a curve in phase space. All orbits in phase space (i.e. the phase portrait of the system) are just level curves of the Hamiltonian. In Lecture 1, we plotted the phase portrait for the simple pendulum, which we reproduce in Figure 1 as an illustration of our discussion. WebThis is another great question. In the video here, Sal uses a horizontal line through the phase diagram. But, it doesn't have to be horizontal. Imagine a vertical line through this …

WebNov 4, 2024 · The energy is considered to be "latent" because it is essentially hidden within the molecules until the phase change occurs. It is "specific" because it is expressed in terms of energy per unit mass. The … WebFor example, once compounds like CO2 ( dry ice) that have extremely low melting/freezing points are heated, they undergo sublimation and turn directly into gas from their solid state. Another example is the process through which snow is formed in clouds.
