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 unit also explains that when matter combines, a mixture may form. Properties of gases gaseous molecules travel at high speeds in all directions and mix quickly with molecules of gases in the air in a process called diffusion. The pressure scale is distorted to represent the large range in pressures given in the problem, so the liquidsolid curve looks different from the one shown in figure 12. Learn about ice, liquid water, water vapor, evaporation, condensation, boiling, and freezing. The attractions between the molecules are not strong enough at that speed to keep them close together as a liquid or a solid.

Includes takehome instructions and a grading rubric for. Quiz yourself on solids, liquids, and gases dk find out. Flammable gases, aerosols, liquids, or solids flammable pyrophoric liquid or solid oxidizer pyrophoric gas pyrophoric oxidizer liquid, solid or gas compressed gas. In this process a liquid changes into a solid on cooling.
When the liquid is cooled the movement of its particles will decrease and they. Particles are far apart and are in constant random motion. Introduce children to the science journal, discussing the format and doing a. Why are some molecular compounds solid while others are gaseous and others are liquid at room temperature. Solids, liquids and gases word mat teaching resources. Next, double underline those parts which explain about compressing substances.
Solid, liquid, gas testing compressibility the earth is mostly solidrock. The unit also explains that when matter combines, a mixture. Use the states of matter headings to sort the cards into three categories. The particles in the hot soup are moving fast and colliding with the vibrating particles in the ice cube. Eg helium atoms water molecules and salt ions, or a mixture of these air. Read the list of words, ponder awhile, identify the state as solid, liquid or gas and name them accordingly. Solid nail lollipop snowflake candy bar dog tags states of matter gas helium steam oxygen liquid orange juice syrup paint glue sports drink grape jam. It can also be used to explain what happens in changes of state figure 1 on the next page. All around us are many different substances, but when we come to study the science of matter, one simple starting point is that all substances are either solid, liquid or gas.
A variety of activity pages related to solids, liquids, and gases. Gases assume the shape of the container, they do not have their own shape. Liquids have no definite shape they take the shape of their container. After all, ice, liquid water, and water vapor are all the same substance. Solubility of gases, liquids, and solids in liquids.
