![]() It’s important to pick the right material for a job based on its chemical and physical properties. (b) A substance in a different state but similar chemical properties is formed. The ability to carry and electric current. In a physical change, the makeup of matter is changed. Changing the size and shapes of pieces of wood would be a chemical change. PDF Physical And Chemical Changes Worksheet 1. Whereas normal steel will rust when exposed to air and water.Īnd wood will react with oxygen if heated. These solutions for Physical And Chemical Changes are extremely popular. Rust has has different properties than pure iron which means that a new substance is created. Physical And Chemical Changes Lab 5 Answer Key. indicates how a substance reacts with something else 2. determined without destroying matter CHEMICAL PROPERTY 1. Like the stainless steel metal in cutlery, which doesn’t react with food and remains shiny after washing. PHYSICAL AND CHEMICAL PROPERTIES AND CHANGES Name Key Identify the following as a chemical (C) or physical property (P): PHYSICAL PROPERTY 1. ![]() Sometimes, we choose the right material based on its chemical properties - which describe how reactive it is. Whereas other materials, like the glass bulb of this lamp, are brittle. Classify the following as being a physical or chemical change. Metal is a good electrical conductor.īoth the metal and the plastic can be easily shaped into long flexible wires - we say they’re ductile. For example, color, shape, mass, length and odor are all examples of physical properties. The electric current can flow through the inner metal part of the wire to light the lamp. Chemical Properties A physical property is observed with the senses and can be determined without destroying the object. As the names suggest, a physical change affects a substance’s physical properties, and a chemical change affects its chemical properties. And plastic has a lower melting point too.īut plastic is a good electrical insulator, meaning we can touch the outside of electrical plugs and wires without getting an electric shock. There are two types of change in matter: physical change and chemical change. Whereas the plastic of the handle doesn’t conduct heat so well, it’s an insulator. Metal is a good conductor of heat, and has a high melting point, making it good to cook with. ![]() Physical properties are the basic features of a material that affects how it behaves in different situations. It’s because of the physical properties of the materials. I’m going to find out why we make frying pans out of metal, and why the case around electrical plugs out of plastic, but not the other way round.
