QUESTION 13 Which of the following statements about kinetic energy (K.E.) is TRUE? The K.E. of a body will double if its velocity doubles. O The K.E. of a body is independent of its mass. All objects moving with the same velocity have the same K.E. As the velocity of a body increases, its K.E. decreases. O None of the above. QUESTION 14 Which of the following properties of a real gas is related to the 'b' coefficient in the van der Waals equation, nRT = [P + (n/m2a)][v-nb)? There are attractive forces between atoms or molecules of a real gas. O Real gases consist of molecules or atoms which have volume. The average speed of the molecules of a real gas increases with temperature. O None of these are related to 'b'. QUESTION 15 A mixture of two gases was allowed to effuse from a container. One of the gases escaped from the container 1.43 times as fast as the other one. The two gases could have been O CO and SF6 O O2 and Cl2 O CO and CO2 O Cl2 and SF6 O O2 and SF6 QUESTION 16 Which one of the following gases would deviate the least from ideal gas behaviour? Ne CH3CI OKr CO2 O F2
