O All objects moving with the same velocity have the same K.E. O 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/v?a)](v-nb)? O There are attractive forces between atoms or molecules of a real gas. O Real gases consist of molecules or atoms which have volume.
