About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators . What is the difference between liquids and gases? Solids cannot be compressed or squashed because the particles are close together and have no space to move into, Liquids flow and take the shape of their container because the particles can move around each other.Liquids cannot be compressed or squashed because the particles are close together and have no space to move into. Task 4a: Read through the slides and watch the video, Describe what happens to temperature during a change of state. They have little curved motion lines to show that the molecules are moving. The three states of matter are solid, liquid and gas. The initial temperature of the ice was taken and recorded in a table (at time zero).

Note: In chapter 5, students will learn that water molecules and coloring molecules are attracted to each other. bbc bitesize states of matter Term 1 / 10 What is the kinetic theory? What are the 5 elements of nucleic acids? The water beads up on the wax paper and stays together when the wax paper is tilted and when the drop is moved around with a straw. Resource type: Lesson (complete) 20 reviews. The three states of matter can be represented by the particle model. The internal energyof particles is the kinetic energy they have due to their individual motions and potential energy due to their positions relative to eachother. biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Solid chunks can form in the milk and cream. In terms of relative energy, gas particles have the most energy, solid particles have the least energy and liquid particles are somewhere in between.

Please consider taking a moment to share your feedback with us. The first to finish is the winner. Students will describe their observations about water on the molecular level using the idea that water is composed of tiny molecules that are attracted to one another. Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). When atoms and molecules lose or gain electrons, they form ions. A material in solid state holds its form and shape. Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam.
