The Princess Bride has been called this generation's The Wizard of Oz. What do you think made The Princess Bride the classic that it is today?View Full Interview
It was first stated by Émile Clapeyron in 1834 as a combination of Boyle's law and Charles's law.
To prove this, we will have to use 3 equations, 2 of them related to ideal gases:(i) pV = nRT(ii) p = 1/3 d <c2>(iii) Ek = 1/2 mv2First of all, an ideal gas has no inter…molecular forces. Thus, its molecules have no potential energy.The internal energy of any system can be defined as the sum of the randomly distributed microscopic potential energy and kinetic energy of the molecules of the system.It is thus evidently clear that the internal energy of an ideal gas is entirely kinetic. (Ep being zero)So, U = 1/2 m <c2> (for an ideal gas)From (i) and (ii), <c2> = 3p/d = 3pV/m = 3nRT/m (d= m/V)Substituting in the appropriate equation, we get:U = 1/2 m (3nRT/m)U = 3/2 nRTFrom the above equation, it can be concluded that for a fixed mass of an ideal gas, internal energy is proportional to the thermodynamic temperature. (fixed mass such that n is constant) (MORE)
Gas powered space heaters are a necessity for many. People who face regular power outages during harsh winter months can't rely on an electrical appliance. Choosing the most a…ppropriate make and model of heater is important. Several factors must be given adequate consideration. These include room size, type of gas (MORE)
Energy prices have never been higher. Oil and gas prices seem to rocket into space much like NASA's now defunct launches. When the prices of these commodities rise, the price …for goods increase as well. Oil and gas are such a vital part of economics and business that when something (MORE)
There is an old song that goes something like this: Beans, beans, the musical fruit. The more you eat, the more you toot. The more your toot, the better you feel. So let's hav…e beans at every meal! Tooting may feel good, but too much of a good thing is (MORE)
What is the change in the internal energy of the gas if 500 cal of heat are added to a gas and the gas expands doing 500J of work?
1. First, you want to convert cal to Joules (cal --> J). To do this, multiply the value of cal by 4.184 (1 cal = 4.184J)500cal x 4.184J = 2092J------------ 1 cal2. Calculat…e the change in internal energy of the gas (ΔU = heat – work).ΔU = 2092J heat - 500J work = 1595J change in internal energy (MORE)
The internal resistance of an ideal voltmeter is infinity ohms. The internal resistance of an ideal ammeter is zero ohms.Since there are no ideal voltmeters or ammeters, we co…nsider the error introduced by adding these instruments to various circuits. In general, practical meters have high enough impedance (voltage) or low enough impedance (current) to not affect the reading more than the instruments accuracy specification, or to not affect the circuit more than is considered acceptable. There are times when this is not true, so we always consider the instrument and its contribution to systemic error. (MORE)
That is a bit of a trick question because it depends on the definition you use for the term "vapor." One definition of "vapor" is that it is synonymous with "gas". By that def…inition, a vapor can very easily act as an ideal gas - just like pretty much any other gas. A second definition of "vapor" is:"diffused matter (as smoke or fog) suspended floating in the air and impairing its transparency" In this case, the suspended droplets or particles will not act like an ideal gas mainly because they are not separate, individual gas molecules. Another way to look at it is that they do not behave as ideal gases because they are far too large to act like the point masses assumed by the ideal gas law. They are usually held aloft by air currents and in the absence of such currents will settle out or coalesce to form droplets that fall when they get large enough. "Vapors" of this sort also display macroscopic properties such as potentially absorbing gasses on their surfaces, agglomerating, nucleating, evaporating, displaying surface tension, acquiring charges from static electricity, etc. nNone of these macroscopic behaviors can be present for an ideal gas.
