The Phase Change There are three main stages of matter, solid, liquid, and gas. With these stages of matter are six types of phase changes, two for each stage. When going from solid to a liquid, it is referred to as melting, and when going from liquid to a solid freezing. In melting, the solid’s molecular movement increases while the attraction decreases. In freezing, the molecular movement decreases while the attraction increases. An example of freezing is water turning into ice, and an example of melting is ice turning into water. When a liquid turns into a gas it is termed vaporization, and when a gas turns into a liquid it is called condensation. In vaporization molecular movement increase yet the attraction decreases, and in condensation the molecular movement decreases yet the attraction increases. An example of vaporization is water boiling until it is gone, and an example of condensation is when droplets of water form on the lid of a teapot. When a gas turns into a solid it is entitled deposition, and when a solid turns into a gas it is seen as sublimation. When a gas goes threw deposition its molecular movement decreases substantially while the attraction increases rapidly. When a solid goes threw sublimation its molecular movement increases miraculously as the attraction decreases promptly. These two phase changes are not as common as the other four, but still happen. An example of sublimation is when dry ice turns back into CO2. An example of deposition is frost in the winter forming on a window.

    Kotter’s Change Phases are an outline of phases that can be utilized to help organizational changes become successful. Kotter’s eight steps or change phases are “1. Establish a sense of urgency 2. Create a coalition 3. Develop a clear vision for the change 4. Share the vision 5. Empower people to remove obstacles 6. Secure short-term wins 7. Build on the change 8. Anchor the change in the corporate culture” (Phillips & Gully, 2014). Each of these steps highlights the ways in which changes can not…

    can quickly change between the different forms of H2O by either increasing or decreasing temperature. We have worked with hot plates and thermometers in other labs before, so we know how to be safe. I wonder what a graph of the changing temperatures over time between the phases would look like. Hypothesis Based on prior learning, I predict that the graph of the water phase changes will not be one straight slope, but instead will plateau, or be flat, and then slope between the change of ice to…

    Phase Change Lab Report by Dylan Norford Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change. Background: The science…

    Heat, Temperature, and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water, while it was boiling in a kettle, as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change, the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly…

    Phase Change Lab Written Response Our objective in our phase change lab was to record observations of the increase in temperature (in Celsius) as water changed from solid to liquid to gas over a hot plate. This lab report will discuss quantitative and qualitative data contained in the lab, how energy is related to phase change in water and an elucidation of how melting point and boiling point relate to the physical properties of matter. This paper will basically outline the lab done in class…

A phasor diagram shows the impact of poor synchronization with the local oscillator. Digital processing is used to remove phase and frequency errors. Since the early days of electronics, as advances in technology were taking place, the boundaries of both local and global communication began eroding, resulting in a world that is smaller and hence more easily accessible for the…

    can see the Moon’s phases even though the Moon doesn’t change. The Moon phases are the different stages of the Moon as it orbits Earth. This cycle is known as the Phases of the Moon. As the Moon circles Earth, the amount of light we see changes. These changes in light that we see are known as phases. As the Moon orbits around the Earth, the changing of light is known as waxing and waning. The phases have to do with the relativity of the Sun, Earth, and Moon. The phases help us determine what…
