Solid is defined as the state of matter wherein the molecules or atoms are tightly packed. It is in a kind of transient state between being composed of the elements prior to ignition and the spent fumes. The boiling point is 1,265 F (685 C), and the melting point is 428.9 F (220.5 C). Solids have a definite shape and volume as the atoms in solid are tightly packed, usually in a regular pattern. Sold, liquid, and gas all have volume and shape. While at temperatures above 100C, water is a gas (steam). Water can occur in three states: solid (ice), liquid, or gas (vapor). This is achieved by compressing the gas, and then expelling it through a small nozzle. A part of the fragrance turns to gas because of air friction and its resultant heat. Liquids and gases flow easily because their particles can move or slide past one another. by Vasaygrace30. KS2 Y4 Science Materials. Now, let's dive into what solids, liquids, and gases are. Liquids and solids are not easily compressible; meaning they have little space between the particles. Gases become liquids; liquids become solids. Y4 English. But metals such as Copper and Iron in . The temperature at which the solid-liquid phase change occurs. Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. 1. Depending on the conditions, a substance may skip a phase, so a solid may become a gas or a gas may become a solid without experiencing the liquid phase. The molecules of a solid are closely packed. This element is a solid. by Khristine2. They fill the space complete in which they are kept. Copy of gas liquid and solid Crossword. View news and stories of selenium solid liquid gas. The molecules are arranged regularly and systematically. GAS.
