A week after the New Moon, the Moon reaches its first quarter, and half of it is illuminated.At waxing gibbous, most of the Moon is visible and only a small part of the Moon is in shadow. At Full Moon, the Sun lights up the entire side of the Moon that faces Earth.It is the brightest phase and marks the transition from the waxing phase to the waning phase.
Play this game to review Science. A car mechanic had a sealed bucket containing a substance in the gas phase. She left the bucket outside over the weekend. When she returned, the substance had changed phase, and the substance was in the liquid phase. What happened to the molecules of this substance?
Phase Change Homework 1) Explain the difference between evaporation and vaporization. 2) Explain what happens on a molecular level when a chemical compound melts. 3) Using this phase diagram, answer the following questions: a) If this substance is at the pressure and temperature of point E and the.

During a phase change, the temperature of a substance remains constant.We commonly observe phase changes from solid to liquid, such as the melting of ice.
Use this lesson to explore how the properties of gases depend on the behavior of the particles involved. Students will love playing with the simulation. Plan your 60-minute lesson in Science or gas (Physics) with helpful tips from Ryan Keser.
Changes of Phase (or State) Back Heat and Temperature Energy Mechanics Contents Index Home. The term 'change of phase' means the same thing as the term 'change of state'. There are four states, or phases, of matter: Solid Liquid Gas Plasma We will not be discussing the plasma state here.
