Erin Gauthier I ’m torn about the cost- benefit analysis between deciding to increase taxes to alleviate pollution and improve the environment. The cost of gas is expensive enough and car companies are employing new tactics to alleviate most of the pollution that cars cause‚ by the use of electric cars‚ cars that have higher gas mileage‚ smaller cars‚ smaller engines and inspection regulations for each automobile to be done every year. As far as raising gas prices‚ I think that will cause more damage

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated

December 10‚ 2012 Gas Prices too high to pay Today gas prices have crept up to just over fifteen dollars a gallon. Due to rapidly depleted resources‚ the price of oil has gone to five hundred and thirty dollars; therefore the final price of gasoline had to increase. This has caused extreme violence to erupt all over the nation‚ especially at the gas stations themselves. People‚ in order just to fill up their gas tanks have had to sacrifice many things in their daily life. Even though most people and businesses

A Visit to Hill Station Our school was closed for summer vacations on 18th May. It was very hot in Delhi. My parents decided to go to Niligiris. I too accompanied them. We packed our luggage and got ready for the journey. We went to Coimbatore by train. The railway journey was rather tiresome. From Coimbatore we went to Ooty by bus. We reached there in the afternoon and put up at a hotel. Ooty is one of the best hill-station of India. It may be called the queen of hill-station. It has many beauty
