No fixed shape‚ has fixed volume‚ flow easily. Gas: when collected into vessels occupies all space inside vessel‚ takes shape of container‚ no fixed shape or volume. Arrangement of particles in solids‚ liquids & gases • Attractive force among particles strongest in solid. Particles are close together& arranged in a fixed pattern. • Weaker attractive force in liquids than solids. Particles not as close as in solid but more closer than in gas. Particles loosely packed ‚ have freedom of moving

Two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas. b. Liquid Solution- contain a liquid solvent in which gas‚ liquid‚ or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution. c. Solid Solution- is a mixture of solids spread equally throughout

a definite shape‚ you can hold a solid rock in your hand. You can push on a solid brick wall. Scientists say a solid is something that has shape. A solid resists any change in its shape. TASKS 2.

Solid has a fixed shape Its particles are tightly held together It can be held in someone’s hand Liquids have indefinite shape and so it can take the shape of any container

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place

What happens when oil does peak? by Joel Bainerman Peak oil is often referred to as "Hubberts Peak"‚ a geophysicist who observed that oil well production followed a bell curve. According to the mainstream‚ convention view‚ peak oil is set to occur around 2006-2008. When peak oil occurs‚ production will decline approximately 3% per year at a time where global demand is increasing at 3% per year. What will all this mean for you and me- the average folk? Which industries will suffer the most- and
