At standard temperature and pressure, or STP, the volume of 4.50 moles of nitrogen gas is 100.8 liters. In chemistry, the volume or space that 1 mole of any gas occupies at STP is given as 22.4 liters, or 22.4 liters/1 mol. By using this information, the calculation to find the volume of 4.5 moles involves multiplying 4.5 mole by 22.4 liters/1 mol.
Continue ReadingAnother method to find the answer is by using the Ideal Gas Law given as P x V = n x R x T, where at STP, the temperature is 32 degrees Fahrenheit or 273 degrees Kelvin, the constant R is 0.082057 L atm/mol K degrees, n is the number of moles and P is the pressure of 1 atm. By expressing the Ideal Gas Law as V = (n x R x T) and substituting for the variables n = 4.5, T =273 K, R= 0.082057, P= 1 atm, it is possible to find the volume as 100.8 L.

Full Answer >When air is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws. When air is compressed rapidly, its volume decreases leading to increase in temperature.
Full Answer >The graph of Charles Law is a graph describing how the volume of a gas changes with respect to its temperature and where the volume is a linear function of the temperature. When the temperature of gas is given in units of Kelvin, the graph intersects the x-axis at 0 K, where the volume is 0. On the other hand, if the temperature is given in units of Celsius, the graph intersects -273 degrees Celsius on the x-axis.
Full Answer >The ideal gas law describes a relationship between pressure (P), volume (V), temperature and number of moles (n) in terms of the gas constant (R) for an ideal gas. The ratio of (PV) to (nT) should be equal to the gas constant as shown in the ideal gas equation PV = nRT. The ideal gas law assumes that the gas molecules are ideal and do not have any volume and that there are no forces acting on them except during collisions. It was designed to understand the effects of pressure, volume and temperature on gases while excluding the variables of real-world conditions.
