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

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

WHAT IS FUMIGATION? Fumigation is the process by which a lethal chemical is released into an enclosed area to eliminate an infestation of pests. This process may be used in order to rid a home or other structure of insects such as termites or roaches‚ but it may also be used when products are being processed for export or import in order to rid the goods of exotic pests and organisms. Fumigants are a unique and particularly valuable group of pesticides that can kill insects where no other form

pressure also increases the risk of the tire exploding. Gas mileage refers to the number of miles a vehicle can travel on a gallon of gas. The gas mileage of a car can be affected by several factors such as the driver’s driving habits and tire pressure. Aggressive and high speed driving will normally result in a higher consumption of gasoline. The tire pressure of a car can also have a significant effect on the distance a car can travel on a gallon of gas. Inflating tires to the recommended air pressure

experiment was to calculate the heat capacity ratio γ for three gases find in three different classes. The three different gases and their classes are; helium which is classified as a monatomic gas‚ nitrogen which is classified as a diatomic gas and carbon dioxide‚ which is classified as a linear triatomic gas. After these experimental heat capacities ratio were calculated they were then compared with theoretical values. Introduction: Heat capacity is a very important concept in thermodynamics. It
