Lab 3 – Gas Laws and Heat Engines Fall 2010 . Name_____ Name_____ Name_____ Introduction/Purpose: In this exercise you will test some of the aspects of the ideal gas law under conditions of constant pressure, constant temperature, and constant volume. Then you will build a heat
Ideal gas constant The gas constant, which is represented by the symbol R, is also known as the universal constant or molar. It is used for many fundamental equations, and this includes ideal gas law. What's the value of this particular constant? Well it is 8.3144598 J/(mol * K). This gas constant is frequently referenced as a product that ...
creativity. Stay organized and use tables and graphs where necessary. - As instructed at the beginning, prepare a 5 minute presentation to be given to your peers on what you learned . Group 1 . Goals: difference between ideal and real gases . Applying the volume correction to the ideal gas law . 1.
The equation of state can be written in terms of the specific volume or in terms of the air density as p * v = R * T or p = r * R * T Notice that the equation of state given here applies only to an ideal gas, or a real gas that behaves like an ideal gas. There are in fact many different forms for the equation of state for different gases.
The equation is usually called the "ideal gas equation of state" and is called the "universal" gas constant. It can be seen that for an ideal gas, the equation for the virial includes only the first term in the power series. When the virial is expressed in specific terms, the corresponding equation is Pv = RT. where v is the specific volume and R is the "specific" gas constant.
Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K −1 ⋅mol −1.
