Assume the gas to be ideal. (i) Calculate the volume occupied by the gas. volume = ________________ m3 (2) (ii) When the gas is compressed to one twentieth of its original volume the pressure rises to 7.0 × 106 Pa. Calculate the temperature of the gas immediately after the compression. Temperature ___________________ K (2) 2 (a) (i) Calculate the mean kinetic energy of krypton atoms in a sample of gas at a temperature of 22 °C. mean kinetic energy ____________________ J (1) (ii) Calculate the mean-square speed, (crms)2, of krypton atoms in a sample of gas at a temperature of 22 °C. mass of 1 mole of krypton = 0.084 kg mean-square speed____________________ m2 s-2 (2) - - - - [Show More]
