The change in energy stored in the gasoline on driving the car should be explained. It should be explained if the energy stored in the gasoline can be reused once it is dispersed to the environment. Concept Introduction: The total energy of the universe is a constant. It means that the energy cannot be created or destroyed. This principle is known as the “Conservation of energy”. There are principle sources of energy as well as different forms of energy or types of energy. The energy stored in a given system is known as “potential energy” whereas the energy possessed by a moving body is known as “kinetic energy”. However, both natural and human processes energy forms can be converted from one form to another form in order to do useful work. Energy is a measure of the ability to do work on the surroundings or by the surroundings.

Question

One liter of N2(g) at 2.1 bar and two liters of Ar(g) at 3.4 bar are mixed in a 4.0 liter flask to form an ideal gas mixture. Calculate the value of the final pressure of the mixture if the initial and final temperature of the gases are the same. Repeat this calculation if the initial temperature of the N2(g) and Ar(g) are 304 K and 402 K, respectively, and the final temperature of the mixture is 377 K.
