States of Matter: Basics

Prior to beginning this lesson, it is important that I get a sense of what my students already think or know coming in, so that I can identify common misconceptions. This lesson emphasizes the importance of visual thinking to build deep conceptual understanding of the topic. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Now that student have experienced and reflected on this anchor activity, it is time for them to delve a little deeper with the use of. Access the site to run the applet, if you have trouble loading it here. All matter is made up of atoms, which are far too small to see directly through a microscope. A gas expands to fill its container that is, it does.

Subject:Chemistry Topic:States Of Matter What is matter? Examples: Water, Mercury, Alcohol Viscosity-a measure of its resistance to gradual deformation by shear stress or tensile stress. A liquid is made up of tiny vibrating particles of matter, such as atoms and molecules, held together by intermolecular bonds. Change the scale back to Kelvin. Students record comments from the class discussion in their notebooks. The point of this activity is to establish the anchor experience for them to refer back to later. More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water which all have different interaction potential. Examples: Water vapor, Hydrogen, Oxygen Plasma seen in ionized gases distinct from a gas because it possesses free electrical charges not bound to atoms or ions cause plasma to be electrically conductive.

Attractive intermolecular forces are known as van der Waals forces. Endothermic Freezing point-temperature at which they turn into solids. Solid is the state in which intermolecular attractions keep the molecules in fixed spatial relationships. As a result, although the particles are intact they can easily slide past each other. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.

Condensation-The process of becoming more dense, in. Together, the simulations promote understanding of gas laws, states of matter, phase change, and kinetic theory. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Explain how a change in temperature affects the pressure inside a container. You may either describe using words or sketch a drawing using a program like Paint. Phase 5 List the three common states of matter in order of highest potential to lowest.

Recognize that energy is absorbed when a substance changes from a solid to a liquid to a gas, and that energy is released when a substance changes from a gas to a liquid to a solid. Most of my grade 9 students were able to finish in just less than one full class period ~45 minutes , though not quite all. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. Here are some of the common takeaways from the class discussion that ensues: 1. Add or remove heat and watch the motion of the molecules as they change phase. Examples: Stars, Lightning, fluorescent lights Melting Endothermic Become liquefied by heat.

. Some liquids resist compression, while others can be compressed. Melting point-the temperature at which the solid melts to become a liquid. They started vibrating, translating, and rotating faster. Plasma is a highly ionized gas that occurs at high temperatures.

Makes grants to address the most serious social and environmental problems facing society, where risk capital, responsibly invested, may make a difference over time. Many forms of energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on the separation between mutually attracting or repelling objects. Push the pump and change the volume of matter in the closed container. You can heat or cool the substances in the container by sliding the bar on the bucket to Heat for fire or Cool for ice. We cannot offer interpretations about citations as this is an automated procedure.

My student goals include: 1. Thus an induced dipole is developed in the other molecule. A gas has no definite shape or volume, but occupies the entire container in which it is confined. A liquid can be expanded or compressed slightly. Surface tension can be broken by adding soap to water. Futhermore, the particles are randomly arranged with small spaces between them.
