Its Properties and its Various Forms Use properties of matter to identify Give examples substance and to of these separate them; properties; and Distinguish between: Show respect physical and chemical for individual properties; extensive and intensive differences. properties; Matter Types of Quote of and Its Physical the Week Properties Properties of Matter Matter is all the “stuff” around us! ✓ It is any substance that has mass and takes up space by having volume. ❑Physical Property ❑Chemical Property ✓ are those properties that can be observed or measured without changing the fixed composition of a substance. Sort the following substances under the three states of matter. SOLID LIQUID GAS SOLID LIQUID GAS Take a moment Find a partner Finally, volunteer to think of your and take turns and share what answers to the discussing you discussed questions below. your answers. with the whole class. Can you stir a solid? Why or why not? Can you hold a gas? Why or why not? Particle Arrangement Properties and Behavior Rigid Tightly packed Fixed shape Arranged in a Fixed volume specific pattern Cannot be compressed Vibrate in position Cannot flow Particle Arrangement and Behavior Properties Close together but has no Not rigid regular pattern No fixed shape Have little free space Fixed volume between them Can be slightly Slide and roll past one compressed another Can flow Particle Arrangement and Behavior Properties Widely spaced Not rigid Travel in straight lines until No fixed shape they bounce off another No fixed volume particle or a surface Can be compressed Move around quickly Can flow Particle Arrangement and Behavior Properties In high temperatures cause the atoms/particles to break apart has a very high electrical into electrons and nuclei. This conductivity mixture of electrons and nuclei a soup of positively act similarly to gas particles, charged particles (ions) moving freely and have no and negatively charged distinct arrangement. particles (electrons). Jake found a mystery substance with the following properties: It follows It flows. the shape of its container. It has a It can be fixed slightly volume. compressed. Draw the arrangement of the molecules Jake found here. Jake found a LIQUID substance! ANSWER KEY It follows the shape It flows. of its container. It has a It can be fixed slightly volume. compressed. ❑Extensive Property ❑Intensive Property ✓ It depend on the quantity of matter or the amount of substance that is being examined or described. ✓ is a property of a physical object that quantifies the amount of matter it contains. ✓ is a measure of the amount of space that a substance or an object takes up. ✓ is the measurement of the extent of something along its greatest dimension ✓ It depend on the quality of matter. These properties do not depend on how much of the substance there is. ✓is the mass per unit volume. ✓ is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. ✓ is the temperature at which a solid changes into a liquid. ✓ is the temperature at which the vapor pressure of the liquid is equal to standard pressure. ✓ is another type of bulk property defined as a liquid's resistance to flow. ✓ refers to how light is reflected from the surface of a substance. ✓ refers to the capability of being pulled or stretched into thin wire by mechanical force without breaking. ✓ refers to the capability of the material to deform under compressive stress. ✓ is the property of solid materials to return to their original shape and size after the forces deforming them have been removed. ✓ describes the property of a material that fractures when subjected to stress but has a little tendency to deform before rupture. ✓ are those properties that come from the ability of a substance to form a new substance with entirely different properties. ✓ how easily something will burn or ignite, is a chemical property because you can't tell just by looking at something how easily it will burn. ✓ is the amount of energy that is released as heat when a substance is burned with oxygen. ✓ this is what takes place by gaining oxygen, losing hydrogen, or losing electrons. ✓ how much a substance can damage an animal, plant, cell, organ, or other organism. oWhat is matter? oWhat are the properties of matter? oWhat is the difference between physical and chemical properties? oHow do extensive properties differ from intensive properties? Classify the following examples as physical or chemical properties: oMelting of ice oDigestion oRusting oEvaporation of water oPhotosynthesis ― ☺
