If the number of gas atoms in a container is doubled, the pressure of the gas doubles (assuming constant temperature and volume). Explain this pressure increase in terms of molecular motion of the gas.
Solution Step 1 of 2 The state of the ideal gas can be determined by the ideal gas equation, Given by PV=nRT Where P, V and T are the pressure , volume and temperature of the gas respectively, R is the universal gas constant and n is the number of moles of gas. Since here it is given; temperature and pressure remains constant.(R is constant) Therefore, P n That is If the number of gas atoms in a container is doubled, the pressure of the gas doubles.
