Physical property

Water exists in all three physical states only on planet earth, the only planet where life exists in the whole of universe. Water supports life on earth due its unique physical properties such as density, temperature variation, reflectivity, surface tension, specific heat, boiling and freezing points, as well as its chemical properties including its polar nature, dissolving ability and capacity to act both as an acid or base. The exceptional physical properties are all attributed to water’s specific chemical structure and bonding. Ice is less dense compared to liquid water and hence floats on top oceans, protecting aquatic life. Water temperature affects dissolved gases concentration, rate of photosynthesis and other metabolic activities, conductivity,…

being its own discrete metal with its own scientific properties was made until years later (“Zinc,” 2016). Therefore, despite its initial use in earlier centuries, zinc was first recognized as a distinct element by Andreas Marggraf, a German chemist,…

Most sulfur is, however, used in the production of sulfuric acid, which is perhaps the most important chemical manufactured by western civilisations.Physical and Chemical Properties. Sulfur is an odorless, tasteless, light yellow solid. It is a reactive element that given favorable circumstances combines with all other elements except gases, gold, and platinum.Sulfur exists in two allotropic forms. Allotropes are forms of an element with different physical and chemical properties. ... Another…

Corrected Text Slide 1: Properties of Iron Learning Objectives At the end of this class session, you will have learned about • Physical properties of Iron • Chemical properties of Iron Slide 2: Introduction After aluminium, iron is the most abundant metal. Iron occurs in the combined state as oxides, sulphides and carbonates. Slide 3: Explanation Physical properties of Iron Teacher: Good morning, students. Student: Good morning, ma’am. Teacher: Today we are going to learn about the physical…

Introduction: You're a student at NFVMS sitting in your 8th-grade science class and you're on the verge of sleep until you're suddenly handed a mysterious vial that inside holds a white mixture. You’re told that you have to figure out what is in it using physical and chemical properties to help you! What is a physical and chemical property you may be asking. A physical property is something you can touch, feel, smell, hear, and see so you’re using your human senses. A chemical property is when…

Purpose: We already knew that the chemical properties of each pure substance are not are not changed after separation in a mixture. The key to find a physical property that one part of the mixture does have but the parts of the mixture doesn’t. In magnetism a magnetically susceptible material is extracted from a mixture depending on a magnetic force. Filtration is separation of an insoluble solid and a liquid. Filtration depends on solubility, the filtrate is the one want to keep (liquid) and…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications. (Chaijamrus &…

Using your results, identify the unknown substance(s). (1 T/I) According to my results the unknown substance that had left Mr.Price in a very critical condition is Sodium bicarbonate commonly termed as baking soda. Who committed the crime? (1 T/I) None of the restaurant staff had pleaded to using Sodium bicarbonate, ergo none of the staff could have been guilty of leaving Mr.Price in a critical condition. Explain how you used the properties from your observation table to make conclusions…

A physical property is a characteristic of a substance that, when changed, does not change the identity of the substance in question. The chemical makeup of the atom, molecule, particle, mixture, or compound does not change. Thus, the substance remains fairly unchanged. Color, state, smell, melting point, and boiling point are all examples of physical properties (teacherlingo.com 1). Density is a physical property. Propane is denser than air, so when released it sinks to the floor. Carbon, one…

Describe the Learning and Innovation 4Cs (i.e., communication, collaboration, critical thinking, and creativity) as well as Life and Career Skills from the Framework for 21st Century Learning that you perceive the students learned and applied as a result of their participation in the Landfill Harmonic project. This video was wonderful, the innovation and the learning that showed in the landfill harmonic inspirational and amazing video were critical thinking, creativity, collaboration and…
