Science; Chemistry; Chemistry questions and answers; For a sample of gas at 25 degrees celsius, the volume was increased by a factor of 2 while the pressure was decreased to one third the original pressure. The equation for the production of methane is C + 2H2(g) yields CH4(g). The root-mean-square speed (u), is the square root of the average speeds of the molecules in a sample of gas at a specific temperature and pressure. When pressure and number of moles of gas are held constant, the volume of a gas and its temperature have a direct relationship - this is known as Charles' Law.

\n\"image4.png\"/\n

So what is the total internal energy of the helium? The temperature of the gas is raised to 273 degrees Celsius and the pressure is increased to 600 kPa. How can I calculate the gas law constant? T = 15 C = 288.15 K. Then we can apply the Charles' law equation in the form where the final volume is being evaluated: V = V / T T If you wanted to predict how temperature will affect the volume of a gas, what other factor must be held constant? { "9.1:_Gasses_and_Atmospheric_Pressure" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()",
