Problem 3: A pressure vessel is filled with a gas at a pressure P = 0.5 MPa and a temperature T = 15 ☌. The volume V = 23.69 L at the normal conditions will be calculated.Įnter the pressure and temperature for normal conditions P = 100 kPa, T = 0 ☌ and click or press the Calculate button.Change the Select an unknown selector to the Volume.The calculator will calculate the quantity in moles that will be used later.Calculate the volume of this mass of gas under normal conditions (P = 100 kPa, T = 0 °С). Problem 4: Calculate the pressure in pascals of 12,8 kilograms of methane (molar mass 16 g/mol) stored at 30 ☌ in the 70-liter storage tank of a methane-powered car. Definitions and Formulas Ideal GasĪn ideal gas is a theoretical gas model, in which a gas is represented by many randomly moving point particles that interact with each other only perfectly elastically, that is when a collision between any two particles occurs, their kinetic energy remains the same and does not convert into any other form of energy such as potential energy or heat. The gas particles are called point particles because it is supposed that they do not take up any space. This theoretical model is useful because it simplifies many calculations and because an ideal gas obeys Newton laws.
