What is the temperature at the end of the process in (a)? (d) What is the pressure at the end of process in (b)? (e) Show both processes in the p-V plane. Problem 2: The temperature of an ideal gas at an initial pressure p1 and volume V1 is increased at constant volume until the pressure is doubled. The gas is then expanded isothermally until the pressure drops to its original value‚ where it is compressed at constant pressure until the volume returns to its initial value.

into the gas that fuels our economy. That is what keeps the gas prices high. When gas supplies are short‚ due to an “inability to refine crude oil into gas efficiently‚” prices increase. This is a component of supply and demand economics. In a positive aspect‚ rising gasoline prices do serve a purpose; they curtail usage so that we do not eventually run out of fuel. If gasoline continued to retain its cheap price‚ despite how much was available‚ people may pull up to their favorite gas station

Grade 3 Story Time by Andrew Collett When our teacher tell us stories at the end of every day‚ we all sit in silence as she takes us far away. To places where wise wizards live in castles in the sky‚ to lands where all the children have wings so they can fly. We all sit in silence we just sit and stare‚ for when teacher tells us stories she makes us feel we’re there.

The reason for having a car is to get you from point A to point B and that’s it‚ no pit stops or a last minute party that you herd was suppose to be bad ass from a person you met 5 minutes ago. Gas is one of the main key for transportations but the way gas prices are going up we should just sell our cars on other things like food‚ people

The respiratory system is a vital factor of gas exchange due to its structures. The structure provides an efficiency to the process. Gas exchange requires an efficient system because it is a process through which blood circulates around the body‚ collects oxygen‚ delivers the oxygen to the organs that require it and releases carbon dioxide. oxygen and carbon dioxide enter and exit the body in opposite directions across a respiratory surface area that supplies enough oxygen to allow the process to

Sodium borohydride Reduction of Benzil Introduction: The Purpose of this experiment is for the students to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols‚ and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product‚ the metal hydride nucleophile of the reducing agents such as LiH‚ LiAlH4

Gas exchange or respiration in humans is the means by which getting oxygen from air into the blood and carbon dioxide out of the blood into the air. Humans must exchange these gases with the environment because oxygen is essential for cells‚ which use this vital substance to release the energy needed for cellular activities. In addition to supplying oxygen‚ carbon dioxide needs to be removed in order to prevent the buildup of this waste product in the body tissues. As breathing is the act or process

Breakdown of the asset. While gas ovens can differ from model to model‚ they operate on similar principles. First lets explain how a typical gas oven operates and which problems may occur. A gas oven ignition system consists of three basic components; the oven controls‚ the igniter and the oven safety valve. In newer models the igniter will be a glow igniter‚ or in ovens that are a few years old‚ an electrical igniter. Old ovens may work with a pilot light igniter. In this breakdown we will

Oils and gas conservation ‚its relevance in daily life: Oil and gas conservation means their better and more efficient use with regard to economic‚ social or environment costs and benefits resulting minimization of wastage and protection of environment. A very high priority is attached by the government to conservation of petroleum products in view of the need to reduce increasing gap between demand for and supply of oil and petroleum products. Government has initiated various
