# what is gas volume

Posted

If we assumed the T and P changed in the reaction, we would not be able to solve the problem. m Example #1: The equation for the combustion of methane is: (a) If 50.0 L of methane at STP are burned, what volume of carbon dioxide will be produced at STP? On the contrary Vs (volume saturated) is the volume a gas mixture would have if humidity was added to it until saturation (or 100% relative humidity). The partial volume of a particular gas is the volume which the gas would have if it alone occupied the volume, with unchanged pressure and temperature, and is useful in gas mixtures, e.g. Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas.

Gas volume produced or consumed is often expressed in million cubic feet (MMcf), (106), and Mcf (thousand cubic feet). According to Boyle's Law, the volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature.. In thermodynamics, the volume of a system is an important extensive parameter for describing its thermodynamic state. Rewrite it as: 2) Everything on the right side is constant, so the n:V ratio must also be constant. $$R = 8.314 \: \text{J/K} \cdot \text{mol}$$, $3.76 \: \cancel{\text{g}} \times \frac{1 \: \text{mol} \: \ce{O_2}}{32.00 \: \cancel{\text{g}} \: \ce{O_2}} = 0.1175 \: \text{mol} \: \ce{O_2} \nonumber$. 100 Comme d'habitude encore et encore de la physique . Answer. Enjoy ! E    n Brief Introduction: The key point to look for are the conditions of temperature and pressure. Worldwide, the cost of gas to the customer is commonly specified in dollars per British thermal unit. ν P a 1.

V However, in a process without a constant volume, the heat addition affects both the internal energy and the work (i.e., the enthalpy); thus the temperature changes by a different amount than in the constant-volume case and a different heat capacity value is required. Assume the final volumes are measured under identical conditions.
